this is the bare minimum I used. NB my partitions have artisanal
GPT labels, yours will probably be different.

thats all I needed to boot to userland & login. I'm reasonably sure that,
assuming you have a default zfs install, you'd not need anything in /etc/fstab
to boot.

Yes it does here. failing that just use `bectl activate`. The -t is
a very nice addition.

Well, we're definitely on the FreeBSD-current email list here, so it's
definitely in CURRENT, and 13.1 RC.
