Fedora NetworkManager and dhclient help request

[Shawn O'Shea]

Ken's referring to this post from me back on July 5th, 2011:
http://www.mail-archive.com/gnhlug-discuss@mail.gnhlug.org/msg29812.html

I've since seen that the proper Red Hat/Fedora/CentOS way to do this is set
DHCP_HOSTNAME in your /etc/sysconfig/network-scritps/ifcfg-eth0 (or replace
eth0 with your correct interface).

Sending the host-name option is enabled by default in Ubuntu.

This blog post, "Make DHCP auto-update the DNS" seems to have a good summary
of the problem and solutions for different platforms.
