Note one strangeness with the m_quota test is that it seems to
pass or fail differently on different systems. On my local
FC15 development system, this version of expect.1 is passing, but
in our RHEL6 test system it has a different number of free blocks
(5709 instead of 5703). It isn't accounted for by just the quota
inodes, since they are 6 blocks each, but I haven't had a chance
to track this down.
In any case, I thought I'd send out at least these basic quota
tests that we have, to avoid duplication of effort, and to give
some baseline for tracking down the quota issues that Ted reported.
Cheers, Andreas
