--- Comment #1 from Allan Jude <allanjude@FreeBSD.org> ---
The normal work-around for this is to import with an altroot, usually by
specifying 'zpool import -R /mnt poolname' or similar.

This approach might make sense, although the new default in FreeBSD systems
created with the installer is for the / partition to be 'canmount=3Dnoauto',
which causes a different problem, where only the non-root datasets get moun=
ted
at import.

I don't know if it makes sense to have a new value for canmount=3Difroot or
something.
