I wonder if it's possible to boot a RAIDframe mirror (RAID-1) using a raid-enabled kernel via pxeboot. I've looked in the raid and raidctl manpages, RAIDframe documentation, and all the OpenBSD list archives. The foremost relevant section I've seen is from the raid (4) manpage:
"RAID filesystems which are automatically configured are also
eligible to be the root filesystem. There is currently no support for
booting a kernel directly from a RAID set. To use a RAID set as the root
filesystem, a kernel is usually obtained from a small non-RAID partition,
after which any auto-configuring RAID set can be used for the root
filesystem."
There's nothing here to suggest that a raid set can't be supported by booting the kernel from pxe. Has anyone else succeeded (or failed) attempting this type of configuration?
I have a gut feeling that this isn't likely to work, but do any undeadly readers have any suggestions for him? It is a neat idea at any rate.

I plan on attempting this soon, but was hoping someone from the community might provide their input on this before I reallocate hardware resources. I'm a little disappointed by your lack of imagination. What's with the sour attitude, anyways?

I manually mirrored to two disks with:
# dd if=dev/rsd0c of=/dev/rsd1c bs=16384 (after using disklabel to copy over label)
Then set redundant boot in the prom:
ok> setenv boot-device disk0 disk1
Then adjust the two /etc/fstab versions as desired (depends on what you're protecting against). I also set altroot so 'daily' will sync up my backup root for me.
