On a fresh default Debian Guest VM, "vi
/etc/dhcp/dhclient-exit-hooks.d/hostname" with the following contents:
vi /etc/dhcp/dhclient-exit-hooks.d/hostname
<start-cut-here>
#!/bin/sh
#
# Update hostname from DHCP
#
if [ "$reason" != BOUND ] && [ "$reason" != RENEW ] && [ "$reason" != REBIND ]
&& [ "$reason" != REBOOT ]; then
return
fi
hostname $new_host_name
echo $new_host_name > /etc/hostname
<end-cut-here>
These changes are unrelated to any other scripts you might have.
Hth.
