This leaves me wondering why we don't test most of the above ;)

Hm is there a reason for the first "-c $TYPE" or even the "daddr 42" in the line just above?
Interesting, I didn't know that a bare "agf" works, but it does (and is documented
as such). fair enough.
It'd be very easy to add just a few more types to this, i.e.: (leaving the extra
type & daddr setting in place for now)
DADDR=`$XFS_DB_PROG -c "sb" -c "addr rootino" -c "daddr" $SCRATCH_DEV | _filter_dbval`
$XFS_DB_PROG -c "type inode" -c "daddr 42" -c "daddr $DADDR" -c "type inode" $SCRATCH_DEV
DADDR=`$XFS_DB_PROG -c "agf" -c "addr bnoroot" -c "daddr" $SCRATCH_DEV | _filter_dbval`
$XFS_DB_PROG -c "type bnobt" -c "daddr 42" -c "daddr $DADDR" -c "type bnobt" $SCRATCH_DEV
DADDR=`$XFS_DB_PROG -c "agf" -c "addr cntroot" -c "daddr" $SCRATCH_DEV | _filter_dbval`
$XFS_DB_PROG -c "type cntbt" -c "daddr 42" -c "daddr $DADDR" -c "type cntbt" $SCRATCH_DEV
DADDR=`$XFS_DB_PROG -c "agi" -c "addr root" -c "daddr" $SCRATCH_DEV | _filter_dbval`
$XFS_DB_PROG -c "type inobt" -c "daddr 42" -c "daddr $DADDR" -c "type inobt" $SCRATCH_DEV
DADDR=`$XFS_DB_PROG -c "agi" -c "addr free_root" -c "daddr" $SCRATCH_DEV | _filter_dbval`
$XFS_DB_PROG -c "type finobt" -c "daddr 42" -c "daddr $DADDR" -c "type finobt" $SCRATCH_DEV
others such as attr, dir, symlink would require more filesystem preparation I guess.
