<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...

alkisg: ok perfect, it works, setting dractu's early_microcode to yes was sufficient :)
07:26

Cool

<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
13:29ben_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

<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

use Ubuntu LTS for a guaranteed out-of-the-box working solution

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.

14:10
<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

<||cw>
16.04?
14:22user8888 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

<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

or, you know, set the time server IP to a local server with dhcp like a real netadmin
19:13

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

<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.
