hey guys, I need to run a "snap remove" command from the ltsp image but Im getting the following error: https://paste.ubuntu.com/p/JmJNBWZQQF/ any ideas how do I run this command? The command runs fine from outisde the chroot

robert45: which ltsp, 5 or 19?
04:01
<robert45>
alkisg sorry forgot to mention, ltsp5
04:02
<alkisg>
Many programs don't run well in chroots, that's why people are moving to VMs, containers like docker or lxc etc
04:02
So one way would be to use a VM or the chrootless mode instead of a chroot,
04:02
another way would be to boot the chroot with qemu or from an nfs-rw client, so that it's normally booted and programs like snap work,
04:03
and the final way would be for you to find out which things need to be bind-mounted in order for snap to work inside chroots
04:03
That last part is why ltsp developers are not recommending chroots anymore, because we don't want to spend time on each of the 50000+ packages separately
04:04
!chroot
04:04
<ltspbot>
chroot: To manage chroots with the new LTSP, see https://github.com/ltsp/community/wiki/chroots
04:04
<alkisg>
This has some pointers on how to boot chroots with nfs-rw or qemu-kvm
04:08
<robert45>
alkisg Im thinking the final way would be the easier one, do you know by chance which things need to be bind-mounted ?
04:08
<alkisg>
robert45: nope, that's exactly what I wanted to avoid and stopped using chroots
04:08
To avoid spending 2 days to find out what snap needs to run in chroots
04:08
<robert45>
ah I see
04:09
<alkisg>
That's why you shouldn't be using chroots with ltsp
04:09
Especially if it's a fat chroot
04:09
*at all, not with ltsp
04:09
At least, with the "chroot" command; it's fine if you're using nfs-rw or lxc
04:21
<robert45>
:/
04:22
alkisg cant I mount squasfs inside chroot neither?
04:22
<alkisg>
It should be possible, with the appropriate bind-mounts
04:22
But for details, you should ask in the snap forums
04:23
Chroots were fine while all developers cared for their programs to be able to run inside them
04:23
That's no longer the case, and LTSP can't fix the *other* programs to be able to run inside chroots; LTSP users that need that, should contact those program developers
04:24
Or just accept it and boot the chroot with one of the other ways I mentioned
04:24
<robert45>
I understand, thanks
04:24
<alkisg>
With lxc, kvm, real client, nfs-rw etc etc
04:24
Or just switch to VM or chrootless which is a lot easier :)
04:26
<robert45>
I think I found a post from you in snapcraft forums
04:27
<alkisg>
I think you're talking about when I was trying to make snaps run properly on the booted ltsp clients
04:28
That part was solved, it was only a problem for a week or so
04:29
<robert45>
ahh I see

So, I was looking at https://www.kernel.org/doc/Documentation/filesystems/nfs/nfsroot.txt and saw that it supports a lot of "extra" options, including hostname and DNS server:
21:26
ip=<client-ip>:<server-ip>:<gw-ip>:<netmask>:<hostname>:<device>:<autoconf>:<dns0-ip>:<dns1-ip>:<ntp0-ip>

<eddyTV>
Does LTSP19 support all those nfsroot options?
22:12
<vagrantc>
initramfs-tools supports most of them, not sure about dns and ntp
22:13
and ltsp19 on debian-based systems leverages initramfs-tools ... i think.

Hmm. I may give it a try. Alkis' answer in https://github.com/ltsp/community/issues/63#issuecomment-557908321 only goes up to <netmask>...
23:16
When a system is booted with GRUB, you can specify a `gfxmode` parameter, which GRUB uses (along with `gfxpayload`, https://www.gnu.org/software/grub/manual/grub/html_node/gfxpayload.html) to configure the video for the kernel so you can use something like https://wiki.debian.org/plymouth to get a "nice" screen while booting
23:17
Is there any way to do that with iPXE?
