Ok, we should probably just add a filter for these so that it'll work
on older versions.

Hm I'm still woefully unfamiliar with quota intricacies.
It seems that after quotaon -f, repquota fails on xfs but works for ext*?
Not sure if that's intended...
Also is there a reason to disable quota before repquota? Is disable/enable
around quotacheck enough?
Hm on ext* I'm also getting differences from the expected output; I suspect
due to selinux xattrs. I'll try to get that fixed up.

It's regenerated at mount time if needed. I don't know that we have a
method to force this recalculation... I guess mounting with quotas disabled,
unmounting, then mounting again w/ quotas on will do it.
