(I assume you're talking about the POSIX ACLs implementation at
http://acl.bestbits.at/ . Following is from Andreas Grünbacher's
write-up at http://acl.bestbits.at/problems.html .)
ext2 doesn't seem to have been a problem; ext3 for a long time _had_ a
problem with machines where ACLs/extended attributes were in use, _with_
quotas, _with_ SMP support -- but that's now believed to be fixed.
Linux NFSv2 code doesn't support the ACCESS call to set/retrieve ACLs,
but there's a patch for the Linux NFSv3 client, as well as for the two
server-end alternatives. The bigger problem for heterogeneous sites is
that there's no agreed-upon standard in the NFS definition for exactly
how ACCESS is to be implemented, so such tend to be vendor-specific.
