There's currently a bug in how default grace periods get set up
before the very first quotacheck runs; we try to read the quota
inodes before they are populated, and so the grace periods remain
empty.  The /next/ mount fills them in.  This is a regression test
for that bug.

If this's xfs specified case, I think "_require_xfs_quota" might be better then
_require_quota, at least it checks "XFS_QUOTA_PROG" and some xfs specified
things.

BTW, do you think "_require_xfs_quota_foreign" can help this case to be a
generic case?

I think $XFS_QUOTA_PROG would be better than using xfs_quota directly.

Hmm... but if the bug is on the default grace time itself, and different
filesystems have different default timers, then I think a xfs specified case
would be better. I don't have a better idea to make it a generic case.

The case from me:
  [PATCH 1/2] generic: per-type quota timers set/get test
Although it trys to test default quota time too, but I think it can't verify
this bug properly, especially if the default time isn't correctly at beginning.
Feel free to correct me, if you have a better idea:)

Thanks,
Zorro

Now I'm confused.  This bug disappeared while I was gone last week.
I'll look into it more, I guess.

Thanks,
