>Description:
	When running dhclient, it overwrites /etc/resolv.conf without
	backing it up somewhere. This can be a bit annoying when one
	still needs that file for later use. :)

>How-To-Repeat:
	Get some DHCP server, touch /etc/dhclient.conf, boot to
	single user mode, "dhclient ep0" (in my case), then look at
	/etc/resolv.conf.

>Fix:
	Backup /etc/resolv.conf (only if a backup doesn't already exist, 
	so it doesn't get overwritten by a dhclient-generated one).
