| 05:17 | <alkisg> vagrantc: hi! I'd like to see if I can make a squeeze thin chroot work with up-to-date Ubuntu servers. nbd-client does have an appropriate backported version, is a backported ltsp-client all we're missing?
| |
| 05:18 | Now that ltsp-update-kernels can extract the kernel+initrd from inside the squashfs image, I can put a 200 mb image somewhere and tell the users to just wget it and run ltsp-update-kernels...
| |
| 05:19 | reasons: work with older graphics cards, and work better with 128 mb ram clients
| |
| 05:22 | Hmmm although I'd need Lenny for good support of really old nvidia clients... http://packages.debian.org/wheezy/nvidia-kernel-legacy-71xx-source
| |
| 05:26 | ....or Ubuntu Hardy 8.04, https://launchpad.net/ubuntu/hardy/i386/xserver-xorg-core... that sounds like fun :D

| 05:50 | <vagrantc> alkisg: squeeze has the backported ltsp-client packages from wheezy
| |
| 05:51 | hardy hurts my brain
| |
| 05:51 | at least squeeze has security support for a few more months
| |
| 05:51 | <alkisg> For those cards, it's either Lenny or Hardy :)
| |
| 05:51 | Parker955_Away has joined IRC (Parker955_Away!~parker@74.112.203.151) | |
| 05:51 | <alkisg> Squeeze has a very "new" xorg version which is incompatible
| |
| 05:51 | Parker955_Away has left IRC (Parker955_Away!~parker@74.112.203.151, Remote host closed the connection) | |
| 05:52 | <alkisg> Those cards need xorg 1.4
| |
| 05:52 | Well, unless I can install xorg 1.4 in squeeze...
| |
| 05:52 | <vagrantc> this also reminds me of the idea to autobuild downloadable LTSP images
| |
| 05:52 | which i never got around to
| |
| 05:52 | <alkisg> The problem with 8.04 is that squashfs uses an incompatible format
| |
| 05:53 | I don't know when the format was changed exactly... I don't know if lenny is affected too...
| |
| 05:53 | Where can I see if mksquashfs was updated in lenny-backports? I can't find lenny-backports...
| |
| 05:54 | <vagrantc> lenny has been deprecated for quite some years...
| |
| 05:54 | <alkisg> http://archive.debian.net/lenny-backports/ltsp-client
| |
| 05:54 | <vagrantc> yeah
| |
| 05:54 | Parker955_Away has joined IRC (Parker955_Away!~parker@74.112.203.151) | |
| 05:55 | <alkisg> I think we have about 1000 graphics cards of that era... and nouveau makes them leave trails etc, they're not in a working state with recent releases
| |
| 05:56 | And the memory requirements with lenny or hardy would be much better... I'm thinking it would be worth it to spend a couple of days to create one single old chroot...
| |
| 05:58 | https://lists.debian.org/debian-backports/2010/04/msg00061.html
| |
| 05:59 | I think that refers to the squashfs issue I was talking about... if so, it's possible to build a lenny squashfs image from a trusty server... /me will try that :)
| |
| 05:59 | <Ark74> alkisg, one question
| |
| 06:00 | <alkisg> Ark74: shoot
| |
| 06:00 | <Ark74> if i have installed local apps, but i don't use `"LOCAL_APPS_MENU" = TRUE' on lts.conf then... am i using the benefit of the local app or don't?
| |
| 06:01 | i mean using less bandwith
| |
| 06:01 | <alkisg> You can only use them manually, i.e. if you run things with ltsp-localapps in front
| |
| 06:01 | So e.g. ltsp-localapps firefox would make firefox use less bandwidth *if* you have it installed in your chroot
| |
| 06:01 | vagrantc: it's still possible to install lenny and update it with lenny-backports, I'd just need to switch to the "archives" mirror, right?
| |
| 06:02 | <Ark74> alkisg, even when there is no `"LOCAL_APPS_MENU" = TRUE' on the lts.conf?
| |
| 06:02 | <alkisg> Ark74: yes, ltsp-localapps works without the menu
| |
| 06:02 | It's the command that the menu uses
| |
| 06:04 | <Ark74> alkisg, so what's the difference between `firefox' and `firefox (ltsp12)'? <-- for example
| |
| 06:04 | less use of resources on the server?
| |
| 06:04 | <alkisg> In the title bar? the first runs on the server, the other on the client
| |
| 06:05 | Less resources on the server and on the network, more on the client
| |

| |
| 06:05 | <alkisg> Read the theory there ^
| |
| 06:05 | <Ark74> alkisg, i've read the theory but in practice i really can't tell the difference :-/
| |
| 06:06 | so i was mixing things on my head
| |
| 06:06 | <alkisg> Try watching a youtube video and run `top` on the server while doing so
| |
| 06:08 | * alkisg tries: sudo debootstrap lenny /opt/lenny http://archive.debian.org/debian :) | |
| 06:08 | <Ark74> so if i'm only taking care of the network traffic i could just install `firefox' on chroot and run from the server then, right? not calling the app from the client

| 06:10 | <alkisg> I don't understand your question. What are you trying to accomplish?
| |
| 06:12 | <Ark74> Make lighter the network traffic on a 10/100 Mbps network
| |
| 06:12 | by using local apps
| |
| 06:13 | but... the machines are really slow if using the apps from the client (local-apps-menu)
| |
| 06:13 | <alkisg> What are your client specs? What RAM, CPU, disk do they have?
| |
| 06:13 | <Ark74> 128 MB, 1.5 Ghz, 20 GB more of less
| |
| 06:14 | <alkisg> 1.5 GHz? What cpu is that?
| |
| 06:14 | P4? P4 M?
| |
| 06:14 | <Ark74> Pentium 4
| |
| 06:15 | some Celeron
| |
| 06:15 | IIRC
| |
| 06:15 | <alkisg> How many clients?
| |
| 06:15 | <Ark74> 10
| |
| 06:15 | <alkisg> What server CPU?
| |
| 06:15 | <Ark74> Core i5
| |
| 06:15 | <alkisg> Which one?
| |
| 06:15 | http://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i5-3210M+%40+2.50GHz
| |
| 06:16 | <Ark74> one sec
| |
| 06:16 | <alkisg> Average CPU Mark: 2808
| |
| 06:16 | *3808
| |
| 06:16 | <vagrantc> alkisg: i honestly haven't used archive.debian.org, but yeah, in theory it's still possible
| |
| 06:17 | * alkisg thinks it'd be nice to write an "LTSP advisor" wizard in the ltsp.org site, | |
| 06:17 | <alkisg> which would advice people on how to best invest their money to have better performance with ltsp...
| |
| 06:17 | E.g. Ark74 now needs a gigabit switch with 60 €
| |
| 06:18 | <Ark74> but all the NIC client's s are 100 Mbps, wouldn't it matter
| |
| 06:18 | <alkisg> Ark74: sure it does
| |
| 06:18 | <Ark74> '
| |
| 06:19 | <alkisg> 100 mbps servers sends 10 mbps to 10 clients
| |
| 06:19 | 1000 mbps server sends 100 mbps to 10 clients
| |
| 06:19 | It's 10 times faster...
| |
| 06:19 | Ark74: so. Run firefox, youtube etc on 1 client. See how fast it goes.
| |
| 06:19 | Then, run youtube in 10 clients. See how slow it goes.
| |
| 06:19 | <Ark74> even when the server send 10mbps, the clients won't be able to get that much info
| |
| 06:20 | <alkisg> When you upgrade your switch, the 10 clients will go as fast as the 1 client went in the first try.
| |
| 06:20 | <Ark74> so far the network runs "fine"
| |
| 06:20 | <alkisg> (08:19:47 πμ) Ark74: even when the server send 10mbps, the clients won't be able to get that much info => you have 2 mistakes there
| |
| 06:20 | First mistake, the server will send 1000 mbps
| |
| 06:20 | <Ark74> streaming youtube using Epoptes works fine xD
| |
| 06:20 | <alkisg> The clients will get 100 mbps
| |
| 06:21 | <Ark74> sorry i ment 10 MBps
| |
| 06:21 | <alkisg> Ark74: let's speak in mbps, it'll be easier
| |
| 06:21 | <Ark74> ok
| |
| 06:21 | <alkisg> Why wouldn't the clients be able to get 100 mbps?
| |
| 06:21 | vagrantc: I've built a lenny chroot on 12.04 :) Continuing with installing stuff in it... :)
| |
| 06:23 | Ark74: we have 500 schools here using ltsp. Half of them use the method with the switch we're talking about.
| |
| 06:23 | <Ark74> i thought that the NIC server will run at the same speed as the NIC clients
| |
| 06:23 | <alkisg> The other half uses full gigabit
| |
| 06:23 | Ark74: what server NIC?
| |
| 06:23 | lspci -nn -k | grep -A 2 Ethernet
| |
| 06:24 | <Ark74> the server has a gigabit nic
| |
| 06:24 | <alkisg> It matter which one, please run that command
| |
| 06:24 | (if you have access)
| |
| 06:25 | <Ark74> sorry not right now :(
| |
| 06:25 | what should i look for?
| |
| 06:26 | <alkisg> There's an issue called "flow control"
| |
| 06:26 | If you have intel or realtek, you can buy cheap switch with 60€
| |
| 06:26 | If it's atheros or marvel, you need expensive managed switch that can disable flow control
| |
| 06:26 | Or, to buy an intel graphics card on the server
| |
| 06:27 | *network
| |
| 06:27 | <Ark74> ohh yeah, i remember that that topic on the list, last month i gess
| |
| 06:28 | so no need to replace the whole network, just the switch and the wire from the server to the switch
| |
| 06:28 | both gigabit
| |
| 06:29 | (or the switch with one gigabit port)
| |
| 06:29 | <alkisg> vagrantc: so... starting with `debootstrap`, and installing ltsp-client afterwards, should I have everything that's needed? So e.g. if I'm missing the kernel, would you want me to report that so that you fix it in the packaging?
| |
| 06:30 | Ark74: yes, and usually the cable doesn't need to be replaced, category 5e is fine
| |
| 06:30 | <vagrantc> alkisg: i think it still depended on a lot of manual configuration from ltsp-build-client
| |
| 06:30 | <alkisg> vagrantc: the newer 5.5 one
| |
| 06:30 | Selveste1 has joined IRC (Selveste1!~Selveste1@static-5-103-136-165.seas-nve.net) | |
| 06:30 | <vagrantc> alkisg: i don't think that'll work in lenny ... aufs support was ... complicated.
| |
| 06:31 | <alkisg> Over nfs, not over nbd
| |
| 06:31 | Right?
| |
| 06:31 | <vagrantc> either way
| |
| 06:31 | <alkisg> Ah
| |
| 06:31 | <vagrantc> we're talking about software from what, 4 years ago?
| |
| 06:31 | my memory isn't solid on this :P
| |
| 06:31 | <alkisg> Yup
| |
| 06:32 | vagrantc: do you think 8.04 has better chances?
| |
| 06:32 | It was using nbd/aufs at that point...
| |
| 06:32 | * vagrantc makes no claims | |
| 06:32 | <alkisg> OK I'll start with lenny first :)
| |
| 06:35 | vagrantc: lenny-backports is a component that I need to add to my sources.list, right? I don't see it as a subfolder there though: http://archive.debian.org/debian/dists/lenny/
| |
| 06:35 | <Ark74> alkisg, thanks it helped me a lot. so far the network is running fine but in case we keep adding clients i wanted to be prepared :)
| |
| 06:36 | <alkisg> Ark74: you can make your clients run 10 times faster with 60€, if you don't want that, ok
| |
| 06:37 | <vagrantc> alkisg: it wasn't officially part of the debian archive until... squeeze?
| |
| 06:37 | <alkisg> Ah
| |
| 06:38 | <vagrantc> http://archive.debian.org/debian-backports/dists/
| |
| 06:38 | bbut there it is :)
| |
| 06:38 | <alkisg> Thanks!!!
| |
| 06:38 | * vagrantc is slightly scared | |
| 06:38 | <Ark74> | |
| 06:38 | <vagrantc> alkisg: so you're going to try to backport 5.5, too?
| |
| 06:39 | <alkisg> Yup
| |
| 06:39 | <vagrantc> 60 euro for a 10/100 switch with 1-2 gigabit ports?
| |
| 06:39 | <alkisg> Yes, a 16 port one
| |
| 06:40 | <vagrantc> wow. i got mine for under US$25 :)
| |
| 06:40 | 24+2
| |
| 06:40 | <alkisg> Second hand?!
| |
| 06:40 | <vagrantc> yeah
| |
| 06:40 | <alkisg> Ah, ok
| |
| 06:40 | <vagrantc> it's kind of overkill for my home network...
| |
| 06:40 | <alkisg> vagrantc: if I want to `debuild -b` ltsp 5.5 in trusty, but have it think that I'm on debian so that it creates the packages with the debian set of dependencies... is there any environment variable I can set to do that?
| |
| 06:41 | <vagrantc> alkisg: no
| |
| 06:41 | <alkisg> Meh :(
| |
| 06:41 | <vagrantc> you'll have to mangle the packaging
| |
| 06:42 | you could configure dpkg-vendor to at least temporarily pretend to be debian
| |
| 06:42 | <alkisg> Thanks... ok first I want to try the squashfs support
| |
| 06:50 | Filesystem on bin.squashfs is (4:0), which is a later filesystem version than I support!
| |
| 06:51 | Let's see what the backports can do about that :)
| |
| 06:51 | khildin has joined IRC (khildin!~khildin@ip-80-236-242-37.dsl.scarlet.be) | |
| 06:58 | <alkisg> About the aufs support, that part is easy, we can just use `nbd-server -c` (cow) on the server :)
| |
| 07:00 | <vagrantc> you've got that working ok?
| |
| 07:01 | <alkisg> vagrantc: I've tried it manually 2 years ago, it was working fine
| |
| 07:01 | spectra has left IRC (spectra!~spectra@debian/developer/spectra, Quit: ZNC - http://znc.sourceforge.net) | |
| 07:01 | <alkisg> With a symlink in /tmp so that it creates temp files in /tmp, not in images
| |
| 07:02 | spectra has joined IRC (spectra!~spectra@debian/developer/spectra) | |
| 07:02 | <vagrantc> alkisg: so nbd-server exports the file from /tmp ?
| |
| 07:03 | <alkisg> Yes
| |
| 07:03 | It was manual, I didn't care much for the "proper way to do things"
| |
| 07:03 | * vagrantc sometimes cares too much for the proper way | |
| 07:03 | <alkisg> We can use a symlink from /var/ to make it better
| |
| 07:04 | I.e. symlink it to a (mktemp -d) directory on the first time it's used
| |
| 07:04 | We can do the same with the /tmp/nbd-server dir we're using now
| |
| 07:04 | Because that's improper as well...
| |
| 07:05 | vagrantc: does a `linux-image-486-bpo` exist, or do I manually have to specify the version, e.g. linux-image-2.6.32-bpo.5-486 ?
| |
| 07:07 | <vagrantc> probably manually specified
| |
| 07:07 | <alkisg> Thanks... so, what I meant about nbd was:
| |
| 07:07 | exportname = /var/run/ltsp/swap/%s
| |
| 07:07 | prerun = nbdswapd %s
| |
| 07:07 | And /var/run/ltsp/swap is a symlink to $(mktemp -d) created on the first time nbdswapd runs
| |
| 07:08 | And we can do the same with /var/run/ltsp/nbdroot, for cow root
| |
| 07:08 | <vagrantc> so it'll be recreated on reboot ...
| |
| 07:08 | doesn't nbd-server usually run as nobody or a specific user?
| |
| 07:09 | <alkisg> Yes, we can work around that though if we put the symlink somewhere where we have code that runs as root, and chmod it later, e.g.
| |
| 07:10 | from ltsp-server postinst, we can create a dir in /var/lib/ltsp/nbd, owned by nbd
| |
| 07:10 | And have the nbdswapd script create the symlinks inside there, well at least until wouter implements putting the cow files elsewhere
| |
| 07:12 | Wow, we have /var/lib/ltsp-client-setup/, no idea why...
| |
| 07:15 | Hehe, there's aoe support in the lenny kernel :D
| |
| 07:16 | <vagrantc> oh, here we go...
| |
| 07:16 | <alkisg> $ modinfo ./lib/modules/2.6.32-bpo.5-486/kernel/fs/squashfs/squashfs.ko
| |
| 07:16 | description: squashfs 4.0, a compressed read-only filesystem
| |
| 07:16 | Coooool :)
| |
| 07:16 | (4.0 is needed to decompress current squashfs images)
| |
| 07:17 | * alkisg puts his Indiana Jones hat on, and continues exploring ancient history... | |
| 07:50 | <alkisg> Meh, that's why I don't like .c in LTSP... need to compile ldm with older libc... compiling...
| |
| 07:51 | LTSP 6 should be extremely easy to backport though :P :D
| |
| 07:56 | Choosing Lenny instead of 8.04 was a wise decision, the backports are a lot better there, I wouldn't even have debhelper in 8.04...
| |
| 08:00 | <Ark74> alkisg, so machines with older processors (not having cmov instruction) will have ltsp 5.5 support on lenny some time in the future?
| |
| 08:00 | <alkisg> Ark74: well that's a personal experiment...
| |
| 08:00 | If it goes well, I may put the result in some web site for anyone that would like to download it
| |
| 08:01 | <Ark74> alkisg, nice!

| 08:01 | <vagrantc> wheezy should work on machines without cmov, no?
| |
| 08:09 | <alkisg> I think so
| |
| 08:10 | <Ark74> i just read that a 486 kernel won't need cmov, not sure if there is a 486 wheezy kernel
| |
| 08:11 | (i mean the latest x86 kernel for non cmov processors)

| |
| 08:38 | <alkisg> Hi elias_a
| |
| 08:39 | <elias_a> alkisg: I have a friend who has been collecting old computers for schools and poor people. He has retired and is about to move to Komotini.
| |
| 08:40 | <alkisg> He's been living in Finland till now?
| |
| 08:40 | <elias_a> alkisg: He does not know anything about LTSP but he has already started communicating with the principal of local school.
| |
| 08:40 | alkisg: Yes. He is sort of multicultural... :)
| |
| 08:40 | <alkisg> Nice :)
| |
| 08:42 | <elias_a> alkisg: IMHO the best alternative would be that this frend of mine would fix the computers and the principal would contact you in order to get LTSP running.

| 08:42 | We are talking about 9th primary school of Komotini.
| |
| 08:43 | <alkisg> elias_a: we have local IT support teams for schools where public IT teachers work on them
| |
| 08:43 | So, there's a team called "KEPLINET" that's in charge of supporting that school
| |
| 08:43 | <elias_a> alkisg: Who should they contact?
| |
| 08:43 | <alkisg> I'm head of such a team in Ioannina
| |
| 08:44 | So, when one school wants to do something with its computer lab, they contact their local support team
| |
| 08:44 | *office, better, not team
| |
| 08:45 | <elias_a> alkisg: Could you tell me the office they should contact?
| |
| 08:45 | <alkisg> 2531084556 or plinetrd at sch.gr
| |
| 08:45 | All schools already know those
| |
| 08:45 | <elias_a> Ok.
| |
| 08:45 | <alkisg> The problem is with people that want to help schools and they don't know that they already have IT support offices
| |
| 08:45 | <elias_a> Thanks!
| |
| 08:46 | <alkisg> Then, the head of that office can contact me if he needs help, I'm in a central team that helps all those offices too :)
| |
| 08:46 | elias_a: also give him this link: http://ts.sch.gr/wiki/Linux/LTSP
| |
| 08:46 | It's the main link for the ltsp solution, as promoted from that central team I'm in
| |
| 08:47 | <elias_a> Yes - I have seen that.
| |
| 08:47 | alkisg: I think we will manage with this!
| |
| 08:47 | * alkisg checks http://www.ltsp.org/stories/widget-map/?location=Greece for nearby LTSP installations... | |
| 08:48 | <alkisg> Whoops, nope, komotini doesn't have any. Nearby towns and cities do...

| 08:57 | <elias_a> alkisg: Do you have a hardware specification for the terminals?
| |
| 08:58 | <alkisg> elias_a: thin clients: anything with at least 128 mb ram
| |
| 08:58 | <elias_a> alkisg: Ok. So almost anything will do :)
| |
| 08:58 | <alkisg> and, for p4+ clients that take DDR-1 RAM, it's best to put 1 GB RAM on them and make them fat clients
| |
| 08:59 | <elias_a> Does your fat client implementation uselocal HDD?
| |
| 09:00 | Or are they diskless, too?
| |
| 09:00 | <alkisg> Diskless

It is start from ltsp-client-core, it start manually but not bys itself it boot-time. I've had a look a the script that should start it, but cannot see what the problem is.

| 19:08 | <alkisg> highvoltage: he's probably using another path for it
| |
| 19:08 | Previously it was called "applications.menu", I think, maybe he's using the old name
| |
| 19:08 | I've *just* started using Lenny :D

| 19:10 | <highvoltage> alkisg: I guess security isn't important to them? can new versions of web browsers at least still run on there?
| |
| 19:12 | <alkisg> highvoltage: their choices are, have something that runs on 15 year old PCs with 128 MB RAM, or do the lesson in the whiteboard without computers
| |
| 19:12 | The server will be 14.04
| |
| 19:12 | So yeah new browsers and all
| |
| 19:13 | <highvoltage> ah I see
| |
| 19:13 | it's a pity how big software has become. I don't think the software on my computer gives me much more features than it did during the lenny period
| |
| 19:14 | <alkisg> True... I think what we lack more is a good vnc solution, with which we could have "static" clients that never get updated
| |
| 19:15 | We used to be able to run VNC over dos with 2 MB RAM
| |
| 19:15 | <highvoltage> a while back freerdp and the freerdp server looked promising, but I never got round to trying it out
| |
| 19:16 | <alkisg> I saw their git recently, it doesn't have much activity, especially on the server part
| |
| 19:16 | <highvoltage> but having a pure thin solution like that that's almost as dumb as a TV would be really great
| |
| 19:16 | <alkisg> TVs nowadays have DLNA clients and all.. how hard would it be to just add keyboard+mouse to the mix :-/
| |
| 19:17 | I think we'll see that in the future, smart TVs offering thin/zero client services too
| |
| 19:18 | Ubuntu TV could actually make that happen with the existing hardware
| |
| 19:19 | <highvoltage> the Samsung Android TV's have keyboards/mouse and you can install rdp and vnc clients on them
| |
| 19:19 | <alkisg> They have much hardware acceleration for video decoding, it's a shame not to put that into use
| |
| 19:20 | A better protocol should be employed there... for great results even for video playback on thin clients

| 20:52 | It needs 15-20 MB RAM less than recent distros, but more importantly, it should work with older graphics cards...
| |
| 20:52 | * vagrantc claps | |
| 20:53 | <vagrantc> the cdpingerless ltspfs works too?
| |
| 20:53 | <alkisg> Tested with nbd and nfs. I still have issues but nothing major, e.g. I was able to login with xterm
| |
| 20:53 | I haven't tried those.. it has hal + udev, i'm not sure if it'll make it
| |
| 20:54 | Btw ip=dhcp isn't necessary after all, and neither is initrd=xxx, we can remove them from the command line
| |
| 21:00 | <vagrantc> initrd= gets added by pxelinux
| |
| 21:00 | at least, i thought it did
| |
| 21:00 | <alkisg> I mean this:
| |
| 21:00 | we currently add initrd= ourselves,
| |
| 21:01 | while we could say "kernel xxx, initrd yyy, append => wihout initrd"
| |
| 21:01 | ...then pxelinux *still* adds initrd=xxx, but it's not our fault then, we can file a bug about it
| |
| 21:02 | <vagrantc> pxelinux derives an initrd to pass?
| |
| 21:02 | <alkisg> No no it supports 2 ways to tell it which initrd to pass
| |
| 21:02 | One, with a special initrd yyy line
| |
| 21:02 | Similar to our "kernel xxx" line
| |
| 21:02 | <vagrantc> what's thee problem with the way we do it now?
| |
| 21:02 | <alkisg> Second method, in the append line
| |
| 21:03 | If we put it to the append line, we're telling pxelinux that we want it there
| |
| 21:03 | http://www.syslinux.org/wiki/index.php/SYSLINUX#INITRD_initrd_file
| |
| 21:04 | If we do it this way, we can file a bug report and ask them to not derive/pass the "initrd=yyy" parameter
| |
| 21:04 | Anyways, we can file the bug even before we change our code, and see if they'll accept to commit that
| |
| 21:04 | Details... :)
| |
| 21:05 | <vagrantc> i still don't understand what the problem is
| |
| 21:05 | ip=dhcp is needed to get initrd-less setups to work
| |
| 21:05 | but those are special-cases, and not the default
| |
| 21:06 | <alkisg> How does that work? The kernel supports nfs root without an initramfs?
| |
| 21:06 | <vagrantc> yeah
| |
| 21:06 | <alkisg> Cool, I didn't know that
| |
| 21:06 | <vagrantc> it has to have all the features compiled in, of course
| |
| 21:06 | <alkisg> And I suppose the necessary modules are compiled inside the kernel... nice
