Yes, that should also work :)

Yes, you can try adding "-s" to the kernel "command-line" in GRUB,
and this should boot you into single-user mode, where "root" is
regarded as an interactive user (with password) and not a role.

Alternately, you can boot from Live media (installer), then run
# zpool import -R /a -N -f rpool

This allows you to clean up obsolete snapshots, expand the pool, etc.

You can mount the filesystem, like
# zfs mount rpool/ROOT/openindiana

It would likely appear as "/a" in the Live filesystem; then you
can edit files on this pool and perhaps wipe the user's password
or insert the cryptext from some other source (i.e. /etc/shadow
of live media, with known password for "jack:jack" and such).

When done, don't forget to
# zpool export rpool

So that you can properly boot off it.
