| Booting is a different matter.
I agree, (although if you had a list of alternatives to boot from...)
but, it's usually difficult to explain this to clueless suit type people
who have expectations of what the software they just bought can do.
I don't think many people would want to mirror their boot partition, since
it's pretty static. The people from Periphonics wanted $25,000 (USD 1995) for
a 1 gig scsi drive for the rack mounted Sun that sits in their IVR Box.
Any other drives void the warranty. We decided it was cheaper to void the
warranty.
The disk in the Sun is already pre-partitioned (one big one), and those that
be wouldn't let me re-partition it sanely. Hence they wanted the whole
disk mirrored, boot and all.
