It's not the wrong hostname, it is what was current when the array
was created.
yes, but i think it's the hostname when the initramfs was created for
the installer.
At least we should make sure this is the case. Could
you investigate what the 'hostname' command outputs on the d-i
shell, just before creating an array in partman during the install?
i checked and it behaves like expected:
it reports '(none)' up to the point where i set it to 'file'. afterwards
it reports 'file'.
i installed _without_ RAID and used guided partitioning this time.
after the system is installed i took a look into /target and
there was the hetzner-mdadm.conf
more evidence for the d-i deploys standard initramfs with
broken/suspect/unupdated mdadm.conf:
1) initramfs has an old timestamp (2011-08-27)
and contains a comment that it was autogenerated that day
sha1sum is: a8f016e70843f108ae05ab0ef874eaad231005c8
initrd.img-2.6.32-5-amd64
2) last time i configured two arrays, but mdadm.conf contains three.
my problem is, that i cannot find it on the install medium (or a file
big enough to hold it, tat actually contains it).
There are three ways forward, really:
1. figure out a way by which the initramfs is updated when the
hostname is changed;
there's only one way and it's updating the initramfs when nessessary
(RAID config) and remove it when not needed.
2. make sure the admin knows that changing the hostname requires
telling mdadm;
3. provide a debconf setting to disable the homehost feature
(setting it to<ignore>).
the UUIDs are different, that's why the array don't get assembled.
since you should now be able to reproduce (even without RAID) i'll trash
those VM images.
