I don't but I did test this once...

It should work,  it's not hard to test anyhow.

glibc-2.2.x or later should support 32-bit UIDs (subject says uid64,
XFS doesn't have this and I'm not sure you need it).

Any recent 2.4.x or 2.5.x kernel should work.

Make sure the tools and utilities out there that are quota aware
are linked against a recent glibc.  Pretty much anything less that a
year or two old should work.


I would just make a quick test setup if you have time and test
things.  It more important to test the applications you will likely
run than the 'theoretical' issues I mention above.
