That's what I was hoping to hear. It's likely that I'll end up using NFS 
root kernels for some (if not all) of my partitions on this system, with 
the local disks only used for booting and swap space.

Thanks for the hints; I'm sure I'll wander through the entire config 
file anyway looking for bits I can turn on, and it's likely I won't have 
module support enabled anyway unless I absolutely have to have it.

At this point I'm thinking I'll have one partition whose sole purpose 
will be to bond the two built-in GbE NICs together, run 802.1q VLANS on 
top of the bonded device, and bridge that into the virtual switch inside 
the 720. That partition will probably run out of a ramfs root 
filesystem, since it won't need much :-)

Can anyone point me to some docs that show how Virtual SCSI actually 
gets configured? I've read nearly everything I can find on IBM's site, 
but so far I can't find anything that tells me how the SCSI devices will 
appear to the "Virtual SCSI client" partitions. I'm hoping they can all 
see an assigned portion of the shared SCSI disks, not have to be 
assigned whole disks each.
