not that unusal, disk limits are only implemented for
ext2/3/4, reiserfs and jfs for now, so xfs is not
accounted and thus not limited ..

yes, they are working quite fine for the supported
filesystems ...

The setup was simplified with recent tools, which do
now calculate the used space and save/restore the
current values and limits properly
so what you described should work fine for the
supported filesystems ...

as there seems some xfs boom recently, and folks
start to actually use that filesystem, I'm inclined
to add the missing feature, given that there are a
few folks willing to test that ...
so please let me know if you're interested ...
