IIRC when working with xen I had to boot with live cd, import the
pool, then poweroff (without exporting the pool). Then it can boot.
Somewhat inline with what you described.

On Ubuntu + zfsonlinux + root/boot on zfs, the boot script helper is
"smart" enough to try all available device nodes, so it wouldn't
matter if the dev path/id/name changed. But ONLY if there's no
zpool.cache in the initramfs.

Not sure how easy it would be to port that functionality to solaris.
