what im thinking of is either distrobox or podman being weird

T

tulip•4/28/25, 4:36 PM

nothing seems to be radically different on the image itself

T

tulip•4/28/25, 4:36 PM

maybe that hostname file gets made on

podman build

podman build

podman build

podman build time?

The Renovate digests issue is exactly this. Made Timothee aware, and I'll try to push a fix to gitlab in the next couple days

You could probably steal the skopeo list-tags loop

ok so my 42 machine has a hostname but my LTS one does not.

J

j0rgeOP•4/28/25, 5:45 PM

if we touch an empty hostname file if it's missing that seems to solve the issue

R

Robert•4/28/25, 5:46 PM

The issue I believe is if you create a Distrobox while there's an os-release present, then update the host to an image which remove it, the container fails to start up

J

j0rgeOP•4/28/25, 5:46 PM

update the host to remove what?

R

Robert•4/28/25, 5:47 PM

Perform an update on the host. A recent report said rolling back to a previous update restored the file

J

j0rgeOP•4/28/25, 5:47 PM

yeah I can't replicate on my F42 machine

J

j0rgeOP•4/28/25, 5:47 PM

but my LTS machine is missing the file

J

j0rgeOP•4/28/25, 5:51 PM

Oh interesting!

J

j0rgeOP•4/28/25, 5:51 PM

the machines are DX only

M

M2•4/28/25, 6:20 PM

i do not have an /etc/hostname

M

M2•4/28/25, 6:20 PM

M

M2•4/28/25, 6:20 PM

No static hostname

M

M2•4/28/25, 6:22 PM

I believe instead its getting the default hostname from

/etc/os-release

/etc/os-release

/etc/os-release

/etc/os-release

Something like this?

sgtm, does anyone hate this?

J

j0rgeOP•4/28/25, 6:30 PM

can we toss this in one of the service packages so we can fix lts and bluefin in one place?

No idea on aurora, so far looks to be bluefin only?

The only thing weird is if a user is truly using dhcp for setting hostnames. I would maybe add a stamp file instead for the conditions check

R

Robert•4/28/25, 6:33 PM

Do they not have /etc/hostname files? Or does their

hostname

hostname

hostname

hostname not return what DHCP assigned?

R

Robert•4/28/25, 6:33 PM

I would expect

$ hostname

$ hostname

$ hostname

$ hostname to always give the desired name, which is what the %H does

M

M2•4/28/25, 6:34 PM

i have no idea what takes precedence. If /etc/hostname or a transient hostname

M

M2•4/28/25, 6:34 PM

as in we are making a transient hostname static by writing it to /etc/hostname

R

Robert•4/28/25, 6:35 PM

And also, since we have no idea what caused it, it could happen again, so something more automated than stampfiles would be ideal

I got the /etc/hostname error on my distrobox upgrade in Bluefin LTS, so it's not just F42, this thi
