This may be related to partman-zfs.  For now I've only worried about
adding the missing features and correcting bugs, I think it still has
much room for optimization.

If someone wants to help with this, I suggest instrumenting all calls
to zpool(8) and zfs(8) commands.  I suspect they may be called LOTS of
times in certain situations.

This is a harmless message (see #603380), but I thought the fix made
it to squeeze.

I guess kfreebsd-kernel-di needs an update.

Was your root filesystem missing in fstab too?

Btw, which version of partman-zfs were you using?

That's not correct; on ZFS you mount the dataset from a ZFS pool,
never directly from a physical device.

With legacy mount command this would be:

  mount mypool/myfilesystem /usr

which is equivalent to:

  zfs set mountpoint=/usr mypool/myfilesystem

You can obtain a list of pools and filesystems with:

  zfs list

Or display the status of all imported pools (including their physical
devices) with:

  zpool status

If you want more info I recommend
http://wiki.freebsd.org/ZFSQuickStartGuide as a quick introduction.
