I once (another place, another job) wrote this for Redhat 6.2:
# the hostname comes from the DHCP server, and is stored in /tmp/netinfo
# one small problem; we're running chrooted
HOSTNAME=`/sbin/debugfs -R "cat /tmp/netinfo" /dev/ram0 | \
grep -E 'HOSTNAME=[[:alnum:]-]+' | awk -F= '{ print $NF }'`
if [ "x$HOSTNAME" = "x" ]; then
HOSTNAME = "localhost"
fi
I have no idea if it would work for RH80. An initial %post --nochroot
would be cleaner.
Alternatives would be to include the hostname in the kickstart file, or
use reverse DNS lookups, assuming the box in installed in situ.
Other posts in this thread suggest to me that
use-host-decl-names on;
in your dhcpd.conf might sort things out.
Cheers,
Phil
