Hi Thomas,  Thanks for the reply.

I'll check /sys and grub and see what I can come up with.

One other question this brings up...

I have updated my FAI install and NFSROOT to one of the latest 
versions... however my config still needs to be updated.  I noticed this 
when comparing some of the scripts in my config directory vs those in 
the FAI repo.  Is there any automated process to upgrading the config to 
the latest... at least those scripts that have not been customized? or 
is this a manual process?

I really need to get my config into a git repo so I can merge easier...
