--- Comment #2 from David NewHamlet <wheelcomplex@gmail.com> ---
(In reply to Allan Jude from comment #1)

Thanks for your explaining. Using altroot/canmount=3Dnoauto/import -N for i=
mport
a pool, which has mountpoint=3D/ with a dataset, is a way to avoid shadown =
mount.
I am wared befor sent this report.

However, never be able to shadown mount rootfs from userspace should be a
common rule for all filesystem. This is why I think a work-around is not en=
ough
and send a report.
