I you have some problems, just put the fai.log onto paste.debian.net and tell us on IRC #linux-fai (oftc.net). Then you can get quick help from ohter FAI users. regards Thomas

Have a look at your class/DEBIAN file in your FAI config space. There
should be a line that says:
release=bookworm
I have a DEBIAN.var file that also defines some other variables.
Alternatively, if you want to be able to install multiple distributions
or versions, you can create your own class/BOOKWORM64.var file. It just
needs to contain the 'release'-line from above.
I copied DEBIAN.var to BOOKWORM64.var, then changed the var to
release=bookworm .
I also defined APTPROXY line to be sure file got read. And Actually it
is. But in the console I get a
fcopy: no matching file for any class for etc/apt/sources.list defined
so it seems it copies the one from nfsroot (it should be handled by
scripts/LAST/50-misc , but isn't LAST a bit late?).
So I also added hooks/task_repository/repository.BOOKWORM64 containing:
-8<--
#!/bin/bash
echo < $target/etc/apt/sources.list
# Created by $0
deb $apt_cdn/debian $release main contrib non-free
deb $security_cdn/debian-security ${secsuite} main contrib non-free
EOF
-8<--
But it seems it's not the correct solution, since task_updatebase still
fetches from bullseye :(
Hints?
Tks.

They're kept in the config directory structure that is mounted to /var/lib/fai/config . Not in the nfsroot.

Good. I noticed after answering that basefiles are well under 100MB. But now the install is saying that it's downloading bullseye packages even if I specified class BOOKWORM64.

Re: Single FAI server, multiple Debian versions?
Tks, that's indeed way easier. And more manageable, especially if the files are kept on a dedicated http server => no changes to nfsroot. The con is that the file needs to be saved somewhere on the local system before being extracted, and that could be a problem with small disks, while with nfsroot it is accessible as a normal file and does not need to be copied. Will dig this, too. For now I'm trying to get rid of some spurious error messages (related to PCI addresses that are not available, probably a BIOS issue) that prevent install to automatically reboot.

Re: Single FAI server, multiple Debian versions?
Tks for the fast answer. I'll have to dig a bit deeper (never used debootstrap explicitly), so it will take a bit more to fully understand.
