Since we''re wishing things:
Temporary pool imports, via a flag on zpool.
Pools that are temporarily imported ignore the in-use flag of the pool.
It should not be written either, whether it''s set as in use or not.
This
would allow accessing the pool manually in a multiboot scenario, where
it belongs to one system, but where the user needs occasional access to
it from elsewhere (e.g. FreeBSD 7). The idea behind temporary imports is
to prevent any problems that may occur if the user forgot to export it
when booting back into the main system.
Also, this would allow true read-only mode on pools, since truly nothing
is getting written to disk, unlike currently, where the in-use flag is
written. As side effect enabling ZFS on read-only media.
