Interesting. In FreeBSD fsck(8) works differently for SU-enabled FS, so
having SU as a mount option won't be possible (if we want to protect our
users from a foot-shooting).
And because of the way SU works, it is possible to run background fsck,
as the only problems are unreferenced objects (inodes, blocks, etc.).
