[indiana-discuss] futzing with boot disks, boot blocks, etc with zfs root

I presently have a (b93) system whose root disk is "too small." I know I can make the rpool bigger by something approximating:

# zpool attach rpool c0d0 c5t1
# # wait for resync
# zpool detach rpool c0d0

... assuming that c5t1 is bigger than c0d0.

But I'm not sure about the boot blocks. Do the boot blocks know about c0d0? If so, how can I teach the system that I want to boot from the only "surviving" disk, c5t1?
