It's universal in a fuzzy sense. On RH systems, I have a file named
/etc/dhclient-eth0.conf that contains the
'send host-name "mypc.example.com";' line. This is the inner, or
low-level configuration file. The outer, or high level configuration
file is indeed /etc/sysconfig/networking-scripts/ifcfg-eth0, and the
controlling line looks like
DHCP_HOST=mypc.example.com
and can be set via system-config-network. Of course, your favorite
editor works too.
