Serves me right for not using cut and paste more. :-/

One thing that is still causing problems is that hostname doesn't appear 
to get set to $nodename, at least not until later on.

Where does this get set, and how difficult would it be to move it to 
before iSCSI/DRBD initialization? I can put

hostname $nodename

in drbd-lib.sh, but that seems a bit nasty if there is already a common 
place for all the network initialization.

It still doesn't explain, however, why iSCSI is getting started up even 
though $rootsource is drbd and not iscsi.

This is still ongoing, but I think I have most of the DRBD plumbed in. 
I'm just waiting for a response on a DRBD issue regarding restarting 
from a Primary/Unknown state into a Secondary/Unknown state. If there is 
a built in way to configure it to come back as Primary/Unknown I'd 
prefer to use that, but failing that I'll write a small wrapper to force 
local to Primary if secondary is Unknown.
