Raid and UEFI

[Dave Tyson <dtyson%anduin.org.uk@localhost>]

I currently have a server which has the boot and data disks mirrored using 
raidframe. The O/S filesystems (/, /usr, /var) are all located in raid0a on 
wd0/wd1. data is located 1n raid1a on wd2/wd3. wd0/wd1 layout is standard mbr 
and both disks have bootblocks so the system will boot off either disk. This 
arrangement has worked well for years and (touch wood!) I have never had any 
issues despite disks failing.

I was pondering switching to UEFI and was trying to work out if a similar 
redundant setup is even possible. I can gpt label each wd0/wd1 and put an 
msdos filesystem on dk0 - but what to do with the rest of the disk? Do I 
create a dk1 partition and make it a raid volume and then gpt label the raid 
partition to form the /, /usr, /var areas. Will the bootstrap process be able 
to handle the fact that dk1 is a raid volume and it needs to look inside to 
find the root filesystem etc.
