I haven't heard anything - which is not surprising, since it doesn't sound like many people are using quotas these days.
Does anyone have any general thoughts as to whether this will be dangerous or not ? I know (I assume) that repquota output for my root and www users will be broken, and that's fine - I just want to make sure that as soon as one user goes over 2TB of owned files the filesystem doesn't trash itself.
Can the quota subsystem failing in some way cause data loss / filesystem inconsistencies ?
