Ouch, I was planning to do this so I could run two versions of FreeBSD on
one disk instead of splitting them across two as I had done in the past,
and continue to use a third slice to share /home and other strategic
directories:
slice 0 - FAT
slice 1 - FreeBSD version x.xx (root partition)
slice 2 - FreeBSD version y.yy (root partition)
slice 3 - FreeBSD shared UFS (/share)
So just to make sure that I'm not misinterpreting, even if I install my
boot manager (OS/BS 2.0B8) to allow booting off slice 1 or 2, when the BIOS
reads the boot record of either slice 1 or slice 2, FreeBSD's loader is
going to force-boot off the FreeBSD version installed in slice 1?
Would it be hard to fix this? It's too bad we don't support this setup.
It'd be particularly handy for developers.
I guess I'll just have to fall-back on putting each version on a separate
disk.
