Hostname not persisting #1718

Open git-mann opened 2 months ago

git-mann commented 2 months ago

Describe the bug

When I set the hostname on my system it does not persist after a reboot. I've tried setting the hostname:

to no avail; the output of hostname and the contents of /etc/hostname get reverted back to just: bazzite after a reboot.

("custom.fq.domain" is just a placeholder for my actual fully qualified domain)

What did you expect to happen?

I expected setting the static fully-qualified domain hostname to persist after reboots. I followed the methods described in the FAQ here.

Probably is because of this https://github.com/ublue-os/bazzite/blob/70436fbf02ecd6c2101426e16d10cf4a87067b9e/system_files/desktop/shared/usr/libexec/bazzite-hardware-setup#L267

Your hostname must be smaller than 20 characters, otherwise distrobox will break. bazzite is a fallback for long hostname cases

My hostname was in-fact greater than 20 characters. I tried a shorter one and it worked as expected. This limitation should probably be documented on the FAQ entry I linked so that if others run into this they aren't just treated with the silent failure.

Also is there an issue that could be linked to distrobox's limitation? Thanks!
