| 07:03 | <fiesh> alkisg: ok, playing around with dracut, it seems early_microcode="yes" will just include the microcode in the dracut image
| |
| 07:03 | <alkisg> fiesh: cool; where do you put that?
| |
| 07:03 | <fiesh> alkisg: so one question that I think I never asked... what's the proper procedure to update the kernel and the initramfs? I can run dracut in the chrooted environment and then copy them over
| |
| 07:04 | alkisg: from dracut's source (well it's a script), it just seems to copy everything from the firmware directory directly
| |
| 07:04 | <alkisg> ltsp-update-kernels copies the kernels from the chroot to tftp
| |
| 07:05 | <fiesh> ok, but I run dracut myself in the chroot environment?
| |
| 07:05 | to create the initramfs?
| |
| 07:06 | <alkisg> Hmm, I'm not sure if there's a "hook" that would run `dracut` automatically on kernel updates in gentoo
| |
| 07:07 | <fiesh> ah I even wrote that down, sorry
| |
| 07:07 | <alkisg> It's done automatically in the Debian world
| |
| 07:07 | So yeah, dracut .... maybe -k for the kernel version if it's different from the host...

| 07:26 | <fiesh> alkisg: ok perfect, it works, setting dractu's early_microcode to yes was sufficient :)
| |
| 07:26 | <alkisg> Cool

| 13:28 | <User8888> Had a few questions today about installing this on gentoo
| |
| 13:29 | I’ve got ltspfs and ldm compiled, not sure if make install installs them correctly
| |
| 13:29 | ben_roose has joined IRC (ben_roose!~roose@roose.cs.wichita.edu) | |
| 13:30 | <User8888> Is there a tutorial you have done on what files need to be where? My old hardware doesn’t like anything but Ubuntu 12 or gentoo
| |
| 13:30 | Ubuntu is great and all but I need some more performance
| |
| 13:39 | User8888 has left IRC (User8888!43adfdca@gateway/web/freenode/ip.67.173.253.202, Ping timeout: 260 seconds) | |
| 13:49 | <quinox> Is Gentoo having a second wind?
| |
| 13:50 | I ran it for many many years, quite happily so, but when the hardware of my box dropped dead I haven't bothered with it
| |
| 13:51 | <fiesh> we're using LTSP on gentoo rather successfully
| |
| 13:51 | but it's not really an out of the box solution I guess
| |
| 13:51 | <quinox> Once whenever you googled for a Linux problem you'd end up at Gentoo's wiki 75% of the time
| |
| 13:51 | I haven't seen a Gentoo page pop up in my search results for a long time now
| |
| 13:51 | <fiesh> yeah now it's more Arch Linux's documentation that rocks ;)
| |
| 13:52 | I think Gentoo's user base has declined --- but I don't really miss having all these ricers around

| 13:54 | <User8888> Does ltsp work outta the box on arch?

| 13:59 | <quinox> use Ubuntu LTS for a guaranteed out-of-the-box working solution
| |
| 14:00 | https://distrowatch.com/images/other/distro-family-tree.png ... what's wrong with us O.o

| 14:04 | <||cw> I have a hard time calling some of those separate distros
| |
| 14:05 | simply having a different set of packages installed by default is not enough IMO.
| |
| 14:09 | User8888 has joined IRC (User8888!aed11de0@gateway/web/freenode/ip.174.209.29.224) | |
| 14:10 | <User8888> I’d use a newer buntu if the hardware would let me
| |
| 14:10 | Perfectly good live installer won’t initialize on our hardware but gentoo is just fine
| |
| 14:17 | User8888 has left IRC (User8888!aed11de0@gateway/web/freenode/ip.174.209.29.224, Ping timeout: 260 seconds) | |
| 14:21 | <||cw> 16.04?
| |
| 14:22 | user8888 has joined IRC (user8888!324c8eba@gateway/web/freenode/ip.50.76.142.186) | |
| 14:22 | <user8888> nothing newer than 12.04 works
| |
| 14:23 | new debians dont work either
| |
| 14:24 | I think these servers feel the same way as i do about systemd
| |
| 14:25 | <||cw> are you sure this server is useful? :D
| |
| 14:26 | idk then. you can use an older ltsp i guess. newer really only works on 16.04 out of the box. anything is going to require a lot of manual work
| |
| 14:26 | personally, I run ltsp in a VM
| |
| 14:26 | it's especially useful for testing
| |
| 14:31 | <user8888> ltsp is making a good bit of money right now for me and it really simplifies things alot
| |
| 14:32 | it actually works entirely out of the box on 12.04
| |
| 14:32 | theres even an alternate install that generates the client image during the OS install
| |
| 14:48 | <alkisg> (05:00:22 μμ) quinox: https://distrowatch.com/images/other/distro-family-tree.png ... what's wrong with us O.o => eeesh zooming in that one is a nice way to hang the system for 1 minute :D
| |
| 14:48 | user8888: haha, you make a good bit of money but you can't buy a box that runs 16.04? :D
| |
| 14:49 | user8888: so anyway, if you're not an ltsp developer or a very experienced gentoo user, I imagine it will take you e.g. 50 hours to get ltsp running
| |
| 14:49 | What's your hourly rate? Couldn't you buy a new pc with all that money?
| |
| 14:50 | <user8888> when its a couple thousand you dont just buy a new one
| |
| 14:50 | <alkisg> And btw, is really gentoo significantly faster (e.g. > 10%) than Ubuntu 12.04 in that hardware?
| |
| 14:50 | Why don't you continue running the older Ubuntu?
| |
| 14:50 | <user8888> about 12.5% so far but it started out about 50% slower
| |
| 14:51 | because I can optimize things I dont have access to with ubuntu
| |
| 14:51 | <alkisg> What if you could find the appropriate kernel parameters that would make Ubuntu 16.04 work on your hardware? Would you still be using Gentoo?
| |
| 14:51 | <user8888> possibly because of the performance gain I know is there
| |
| 14:52 | <alkisg> OK
| |
| 14:52 | So, regarding your initial question, no, there's no tutorial on how to set up a recent ltsp in Gentoo, and I don't think `make install` is enough, as the debian/ dir does a lot of things that are not contained in make install.
| |
| 14:53 | I.e. I still imagine it will take you e.g. 50 hours to get it running properly
| |
| 14:53 | If you need professional help, ping me, I'm available for hire
| |
| 14:53 | <user8888> I figured that was true about ltsp, had hope for ltspfs and ldm
| |
| 14:54 | Ill talk to my boss when he comes in cause I do need some help
| |
| 14:54 | <alkisg> You can check the debian/ dir for the things that need to be done
| |
| 14:54 | <user8888> ok
| |
| 14:54 | <alkisg> E.g. udev rules for ltspfs, x-display-manager entries for ldm, etc etc
| |
| 14:54 | I assume you're using a thin client setup?
| |
| 14:54 | And not the ltsp fat client setup we mostly recommend nowadays?
| |
| 14:55 | <user8888> were using the fat client setup
| |
| 14:55 | that also doesnt work outta the box on 16.04 btw
| |
| 14:56 | <alkisg> In fat client setups, the server isn't really important, it can be a cheap pc with 300 euros
| |
| 14:56 | !ltsp-manager
| |
| 14:56 | <ltsp> ltsp-manager: LTSP Manager is a GUI tool that makes LTSP maintenance easy. It's the recommended way to install LTSP in common setups. More info: http://wiki.ltsp.org/wiki/Ltsp-manager
| |
| 14:56 | <alkisg> These instructions are verified to work out of the box in 16.04
| |
| 14:56 | <user8888> had no clue there was a gui to this
| |
| 14:56 | ive been using this software for almost 6 months lol
| |
| 14:57 | <alkisg> Hehe
| |
| 14:58 | <||cw> now I'm curious what this hardware is...
| |
| 14:59 | <alkisg> Yeah I wonder about it cpubenchmark.net score
| |
| 14:59 | <user8888> im not allowed to talk about any of that unfortunately
| |
| 14:59 | <alkisg> I bet I can buy a faster one with less than 500 euros :D
| |
| 15:00 | The score, not the hardware
| |
| 15:01 | For example "score around 12000" doesn't reveal to you that I have an i7, https://www.cpubenchmark.net/cpu.php?id=2874
| |
| 15:01 | <||cw> if it's P4 xeon based, $100 will get you a better one :P

| 18:24 | <b105> Hey guys, I have a bunch of classroom pis (using pinet). The network they need to connect to for internet access won't let them connect because their date/time is 1969, but they want to connect to the internet to get their date/time from a server. Anyone know of a workaround for this other than manually setting the date and time for every single pi?
| |
| 18:26 | <alkisg> !pinet

| |
| 19:13 | <user8888> man even gettting a nfs going on gentoo is a pain in the ass
| |
| 19:13 | i talked to my boss about possibly purchasing some of your time to help us out Alkis
| |
| 19:16 | <alkisg> user8888: nice, my email is alkisg at gmail if you need something private, otherwise here is fine too; or you can also pm me
| |
| 19:18 | <Hyperbyte> <b105> Eat my ass, Alkis <-- friend of yours? :-D
| |
| 19:18 | <||cw> is now
| |
| 19:21 | * alkisg had to google that to see what exactly it meant :D | |
| 19:21 | <alkisg> 1. rude slang To vehemently or furiously scold or reprimand someone, especially in the armed forces. The captain ate my ass out after I came back to the barracks drunk.
| |
| 19:22 | I sound like a captain? :P :D
| |
| 19:37 | <Hyperbyte> No, he was acting the captain obviously.
| |
| 19:38 | I think he meant it in a literal sense. Maybe he was coming on to you? I don't know.
| |
| 19:39 | * alkisg hopes she at least was a woman then :D | |
| 19:40 | <Hyperbyte> Oh maybe she meant it as a thank-you.
