Subject: [PATCH] Fix dhclient in Fedora ramdisks
Copy all of the necessary parts for a Fedora based dhclient to work. This
includes a number of network scripts. Also grab the ip command supplied by
the iproute package, the busybox "ip addr" command was missing the valid_lft
and preferred_lft options.
This will allow the dhcp to work in the ramdisk instead of getting passed the
PXE net config.
