HOSTNAME in nfsroot boot is FQDN

[Justin Cattle]

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,
Just
