Yep - I've done Solaris installs like that for years and it really is

We use grub and have submitted some patches to RedHat for grub RAID install:
We've recently redone those patches inside anaconda et. al. and will
push them up to RedHat soon.
As to disk layout:
/boot is RAID1 in all configurations
/ is RAID1 for one or two disks, RAID5 for 3-5 disks and RAID6 for 6+ disks

We submitted a patch for our "degraded RAID" install. Unfortunately, it
was rejected by RedHat:
I might fight that battle again another day, maybe with a "Yes, I know
what I am doing" flag.

Feel free to take whatever you need. It's all under mezzanine in
SourceForge anonymous CVS (smeserver project) and patches are pushed
upstream when we can.
