Yes, it's working fine here.
You can even upgrade a new environment while you continue working with
the current one with
manageBE create -n <newBE> -s <sourceBE> -p <pool>
manageBE freebsd-upgrade -n <newBE> -p <pool> -r <release>
manageBE activate -n <newBE> -p <pool>
Then reboot into the new BE and complete the upgrade with the
final "freebsd-update install" step. But I needed to
change "chroot /${bootfs}" near the end of the script
to "chroot /${pool}/ROOT/${bootfs}" to get "manageBE freebsd-upgrade"
command to work.
Along similar lines, if you need to do a massive ports upgrade which you
suspect might go pear shaped then you can do it in a new BE without
upsetting your working system:
chroot /tank/ROOT/newBE mount -t devfs devfs /dev
chroot /tank/ROOT/newBE portmaster -a
chroot /tank/ROOT/newBE umount /dev
... then, if all went well, activate the new BE and reboot.
