| 12:35 | <fiesh> hmm it seems ldm finally vanished from gentoo
| |
| 12:35 | and our ltsp was still based on it :-(
| |
| 12:35 | <alkisg> Time to upgrade... :)
| |
| 12:36 | <fiesh> to what?
| |
| 12:36 | <alkisg> ltsp21
| |
| 12:36 | <fiesh> which I guess won't be that trivial under Gentoo? ;/
| |
| 12:37 | <alkisg> Eh, same as ltsp5 was under gentoo
| |
| 12:37 | <fiesh> oh
| |
| 12:37 | <alkisg> Both needed some love
| |
| 12:37 | <fiesh> is there some manual?
| |
| 12:37 | <alkisg> Didn't we spend a week to make ltsp5 run on gentoo?
| |
| 12:37 | <fiesh> yeah something like that
| |
| 12:37 | it's been working like a charm ever since
| |
| 12:37 | <alkisg> Right, something like that would also be needed now
| |
| 12:38 | <fiesh> (I think it was just a day though, or maybe two days, not a full week)
| |
| 12:38 | <alkisg> There's a thread in ltsp-discuss for porting ltsp to other distributions
| |
| 12:38 | *I mean in github ltsp discussions
| |
| 12:38 | And what is needed for each part
| |
| 12:39 | The server would be rather easy, while the client would need initrd and pam integration
| |
| 12:39 | For your setup, you could skip initrd and only integrate pam
| |
| 12:39 | And for the server, you wouldn't need anything apart from a git clone
| |
| 12:39 | <fiesh> hmm can't find the link yet
| |
| 12:39 | what does initrd and pam integration mean?
| |
| 12:39 | there already is an initrd in use
| |
| 12:39 | and I think gentoo does use and support pam out of the box anyway?
| |
| 12:40 | <alkisg> https://github.com/ltsp/ltsp/discussions/197#discussioncomment-988675
| |
| 12:40 | Yes, but each pam configuration is different
| |
| 12:40 | debian uses pam-auth-update
| |
| 12:40 | If gentoo has that, then it might work; if not, then code will be needed
| |
| 12:40 | Each initrd needs different code to set the writable overlay, that part is harder
| |
| 12:40 | It's done for initramfs-tools, but not for genkernel or dracut
| |
| 12:41 | <fiesh> ah hmm ok
| |
| 12:41 | fuck me :-(
| |
| 12:41 | that was bound to happen at some point I guess
| |
| 12:41 | <alkisg> Since noone wanted to maintain ltsp5, yeah
| |
| 12:41 | It's still there if someone wants to :D
| |
| 12:42 | <fiesh> there's no easy replacement for ldm for now? I'm really quite time constrained lately and would much much rather do this over Christmas ors o
| |
| 12:42 | <alkisg> Why would you want to replace ldm? Just keep using it
| |
| 12:42 | ldm was ltsp specific; its replacement was "proper pam integration"
| |
| 12:43 | <fiesh> hmm yeah it somehow vanished from portage?
| |
| 12:43 | or maybe I screwed up something there to be honest
| |
| 12:43 | <alkisg> Put it back, or compile from code etc
| |
| 12:43 | <fiesh> hmm yeah, valid suggestion
| |
| 12:43 | <alkisg> Currently, ltsp21 works with any DM; even with plain vt/login/sudo
| |
| 12:43 | It doesn't need ldm anymore
| |
| 12:44 | <fiesh> due to PAM? that's quite handy
| |
| 12:44 | <alkisg> Yes, due to pam
| |
| 12:44 | It replaced e.g. 2000 lines of code with 200, and it works so much better
| |
| 12:45 | <fiesh> heh that should happen more often in our code base...
| |
| 13:15 | hmm I guess finding ldm-2.2.11.tar.xz is not that easy any more :D
| |
| 13:18 | ah there's https://launchpad.net/ubuntu/+archive/primary/+sourcefiles/ldm/2:2.2.13-1/ldm_2.2.13.orig.tar.gz
| |
| 13:18 | hurray
| |
| 13:31 | alkisg: so maybe we can tentatively keep in mind to get ltsp21 working on Gentoo around Christmas? I'd greatly appreciate that

| 13:38 | <fiesh> well, it seems the update to 2.2.13 broke something... so I might depend upon your help earlier :/
| |
| 14:18 | <alkisg> fiesh: sure, although I have too much on my plate these days, so it would be best to do it asynchronously, e.g. there are time where I have no free time for months...
| |
| 14:19 | Why was your version of ldm removed? Can't you restore it from a backup or an old ltsp image or something?
| |
| 14:19 | It's possible that we had patched ldm for gentoo, so if you're trying with a random upstream ldm, it might not work
| |
| 14:23 | Pitty, I think I erased your gentoo clone that you had sent me (along with its ldm etc) 6 months ago...
| |
| 14:23 | <fiesh> I have the working image here still
| |
| 14:24 | and I copied over /usr/share/ltsp and /usr/share/ldm, but to no avail
| |
| 14:24 | so only the binary seems to differ
| |
| 14:24 | I'll now try copying over the binary as well
| |
| 14:24 | but that's not a maintainable state :-/
| |
| 14:24 | I dont't think we patched the source for ldm for gentoo, did we?
| |
| 14:24 | only script
| |
| 14:24 | s
| |
| 14:25 | alas I don't remember the version of ldm that was installed, and no binary seems to contain that information :/
| |
| 14:25 | <alkisg> No idea, it's been too long, but I do remember that we pushed a couple of patches upstream
| |
| 14:26 | <fiesh> is there a git repository that I could base the gentoo ebuild on?
| |
| 14:27 | <alkisg> I think this one's the latest version: https://git.launchpad.net/~ltsp-upstream/ltsp/+git/ldm
| |
| 14:29 | shored has left IRC (shored!~shored@user/shored, Ping timeout: 265 seconds) | |
| 14:30 | <fiesh> 2.2.19 and then 2.18.06-1?!
| |
| 14:32 | <alkisg> It sounds like vagrant wanted to start using the 2.year.month scheme :D
| |
| 14:33 | <fiesh> lol
| |
| 14:38 | ok, the old binaries work... so I reckon it might just be 2.2.13 is too old. I'll try basing the ebuild on the git repo
| |
| 14:41 | <alkisg> Btw ltsp21 needs no binaries, I guess it might make things easier for you
| |
| 14:41 | It's all shell/python, no c
| |
| 14:52 | <fiesh> that sounds like an improvement, yeah
| |
| 15:00 | alright, the git version works \o/
| |
| 15:00 | got a working ebuild now :-)
| |
| 15:00 | alkisg: thanks for your input!
| |
| 15:04 | <alkisg> np
