| 18:20 | <vagrantc> so ... ltsp initrd includes /etc/ltsp/* ... but then it's copied into the clients /etc/ltsp/ ... if you want to copy whole directory trees into the booted system, do you have to set up a POST_INIT_ABCDE='cp /etc/ltsp/ABCDE /ABCDE' or something?
| |
| 18:21 | well, cp -r
| |
| 18:22 | woernie has left IRC (woernie!~werner@2001:9e8:e242:7e00:4c5d:f54:98e6:c5d4, Quit: http://quassel-irc.org - Chat comfortably. Anywhere.) | |
| 18:22 | <alkisg> vagrantc: exactly! :)
| |
| 18:22 | (or symlink it)
| |
| 18:23 | * alkisg is glad to see vagrantc using ltsp once more! | |
| 18:23 | <vagrantc> no more straightforward way to just drop files into place?
| |
| 18:23 | <alkisg> Well, ltsp image...
| |
| 18:23 | <vagrantc> heh. yeah, nice to be back :)
| |
| 18:24 | for files you might want to edit regularly, though, the initrd + POST_INIT* is pretty much the way to go
| |
| 18:24 | any reason you don't compress ltsp.img ?
| |
| 18:24 | <alkisg> Yeah, it's much faster
| |
| 18:24 | (for the previous remark)....
| |
| 18:24 | ...for the compression =>
| |
| 18:24 | uncompressed, it works anywhere,
| |
| 18:25 | while compressed, it needs to exactly match the existing initrd
| |
| 18:25 | compression
| |
| 18:25 | So e.g. uncompressed + bz2 works, while gzip + bz2 doesn't
| |
| 18:25 | So we'd have to use a different ltsp.img for each chroot/compression/etc
| |
| 18:27 | <vagrantc> ah
| |
| 18:27 | makes sense
| |
| 18:27 | so, if you're using large files, you'll want those in the squashfs
| |
| 18:28 | and have to run 'ltsp image' when they change
| |
| 18:28 | oh, another question ... i've been building the squashfs image without using 'ltsp image' ... seems like the only gotcha i found was i need to include the ltsp package in the image ... any other likely surprises?
| |
| 18:29 | mmdebstrap supports building a squashfs out of the box without root privledges, so i've been experimenting with that a bit
| |
| 18:40 | !shell
| |
| 18:40 | <ltspbot> I do not know about 'shell', but I do know about these similar topics: 'gnome-shell', 'shell-screen'
| |
| 18:40 | <vagrantc> !shell-screen
| |
| 18:40 | <ltspbot> shell-screen: (#1) One way to get local root access to troubleshoot a thin client is to use a shell SCREEN: https://help.ubuntu.com/community/UbuntuLTSP/ClientTroubleshooting#Using%20a%20shell%20SCREEN, or (#2) to enable a root debug shell, add SCREEN_02=shell and SCREEN_07=ldm to lts.conf
| |
| 18:41 | <vagrantc> i'm guessing SCREEN_XX don't work anymore?
| |
| 19:16 | <alkisg> back, reading...
| |
| 19:16 | so, if you're using large files, you'll want those in the squashfs ==> yup
| |
| 19:17 | i need to include the ltsp package in the image ==> you shouldn't even need that; it's injected into the initramfs and rootfs
| |
| 19:17 | mmdebstrap supports building a squashfs ==> ooh cool, let's make a wiki page about that when we get some time
| |
| 19:18 | !learn screen-scripts as https://github.com/ltsp/ltsp/discussions/514#discussioncomment-1258238
| |
| 19:18 | <ltspbot> The operation succeeded.
| |
| 19:18 | <alkisg> vagrantc: ^
| |
| 19:25 | !hash
| |
| 19:25 | <ltspbot> I do not know about 'hash', but I do know about these similar topics: 'LDM_PASSWORD_HASH', 'ROOT_PASSWORD_HASH'
| |
| 19:26 | <alkisg> !ROOT_PASSWORD_HASH
| |
| 19:26 | <ltspbot> ROOT_PASSWORD_HASH: To be able to login as root in vt1, with password "qwer1234", put this in lts.conf: INIT_COMMAND_ROOT_HASH="sed 's!^root:[^:]*:!root:\$6\$p2LdWE6j\$PDd1TUzGvvIkj9SE8wbw1gA/MD66tHHlStqi1.qyv860oK47UnKcafSKqGp7cbgZUPlgyPv6giCVyCSCdJt1b0:!' -i /etc/shadow"
| |
| 19:26 | <alkisg> While for a simple root login, this ^ is fine
| |
| 19:47 | <vagrantc> that works
| |
| 19:47 | although i just ended up adding an /etc/sudoers.d/ appropriate for the configuration
| |
| 19:48 | alkisg: curious ... maybe the ltsp package is pulling in some other implicit dependency then?
| |
| 20:08 | <alkisg> sshfs and the squashfs module
| |
| 20:08 | What error message do you get?
