  I've fixed noisy disable messages in quotaon (without -v flag only errors
should be printed) in CVS. With repquota & disabled quotas it's a bit more
complicated. The problem is that for ext?, reiserfs,... you have to disable
quotas before running quotacheck. Also quotacheck is NOP for XFS - we'd
rather need to call something to really recompute quota usage for XFS. How
that can be done?
