I posted about this problem approximately a year ago. I poked around in
the source code a little but finally just made a workaround by adding a
line to my class script:
echo "${HOSTNAME}" | sed s/\.math\.wisc\.edu//
So you end up with classes for both the fqdn and the hostname. The only
problem with that seems to be that logs are created in
/var/log/fai/<fqdn>/ instead of /var/logs/fai/<hostname>/.
I am a little surprised you're getting this in 5.3.6. I was running
5.0.3 when I had the problem. I create a whole new FAI setup for 5.3.6
and I don't have the problem any more. Are you using 5.3.6 in the
nfsroot? I'm not sure how FAI installs FAI itself inside the nfsroot but
you might be running an older version there. I am also installing ubuntu
zesty instead of xenial but I don't see how that could matter.

Hi,
I've been testing migrating to fai 5 from 4.
I'm currently using fai-5.3.6, on Ubuntu xenial, but with a Debian
stretch nfsroot [ due to lack of dracut support in ubuntu ].
When I build a host, the boot all works ok and the build process starts
fine.
However, the hostname of the instance is somehow getting set to the FQDN.
It sounds like a small problem, but has a knock on effect on some of our
custom class assignment scripts.
I know that dhcp is sending the correct host-name.
It looks like FAI set's the HOSTNAME variable from this script passed
from dhclient:
root 1531 0.0 0.0 21484 1076 ? Ss 10:21 0:00
dhclient -lf /dev/null -cf /usr/share/fai/dhclient-fai.conf -sf
/usr/share/fai/dhclient-fai-script eth0
Am I right in thinking that?
Any ideas on how I can fix or debug this so HOSTNAME is set to the
host-name requested from DHCP?
It's not even obvious to me where the dhcp config for fai that calls
that script is set.
Any help or info is greatly appreciated.
Thanks!
Cheers,
