in fstab and they are normally mounted as /a/b, if /b is not mounted, the various quota utilities will incorrectly operate with the quotas on /a (silently) when operations are attemted on /b. Sync up all the hasquota() routines between all the different quota utilities and change it to detect if the file system we are attempting to perform quota operations on is not currently mounted and warn the user accordingly.
