To an extent. In /etc/rc.d/rc.sysinit there is the following code:
if [ "$HOSTNAME" = "localhost" -o "$HOSTNAME" = "localhost.localdomain" ]; then
<some conditions checked and variables set>
....
eval $(ipcalc -h $ipaddr 2>/dev/null)
hostname ${HOSTNAME}
fi
So if you did not already set that earlier from values in
/etc/sysconfig/network then all that really comes to what, and when,
'ipcalc -h $ipaddr' is doing for a calculated value of $ipaddr.
This picture is a bit more involved than that but this is the main
point. With the current NM you need either to "hardwire" a machine
name in /etc/sysconfig/network or you will end up as
localhost.localdomain.
It sounds like Steve Thompson supplied names in DHCP leases and this
stopped to work. I really cannot tell why without a detailed
investigation. OTOH if you are able to resolve addresses to names,
through /etc/hosts or a local DNS server or whatever then, AFAICT,
with 'network' service this still works in F9 and the current
rawhide.
