Subject: [PATCH] write-ifcfg.sh: add UUID=.. and save the lease files with
the same uuid
As described in https://bugzilla.redhat.com/show_bug.cgi?id=541410#c2,
if you want NetworkManager to take over an interface that you're using
for NFS root (or other network root device), you need to:
a) set UUID=<uuid> in ifcfg-<iface>, and
b) save the lease file as /var/lib/dhclient-<uuid>-<iface>.lease
This patch should make write-ifcfg handle both these things.
