Hmm. Do you happen to know if that applies to Reiser as well (i.e. does
the Cox kernel quota system work with Samba/Reiser without a patch or do
I need to also find a patch for Samba or use XFS instead of Reiser and
then use the XFS/Samba patch??)? If I understand you correctly, then I
would need to not only find a 2.4 kernel that has quota support (or
patch it myself), but find a filesystem/server combination that works
with the quota system that the kernel supports, which apparently becomes
rather tricky with modern filesystems and the current kernel generation
. . . ugh.
