For instance, if a part of the filesystem changes while running quotacheck, I imagine that does not get accounted for. Wouldn't somebody have trouble enabling quotas on a busy filesystem? The quota file would always lag behind the actual filesystem, and one cannot mount read-only because quotacheck must write the quota file. sh
