I got a feature request from a Fedora users https://bugzilla.redhat.com/show_bug.cgi?id=1326527 about displaying "wrong" file system name by quota(1) tool.
If you have multpliple NFS mounts to different mount points, quota(1) tool pick one "randomly" and displays it. Such output can be confusing if a mount point or a file system name contains user's name and the name does not match the current user. (Read the linked request for an example.)
While this cannot be fixed for all cases becaue POSIX does not have a file system ownership, there could be an improvement:
There could be an quota(1) option that would restrict listed file systems to those whose mount point is owned by current user. What's your opinion? I haven't yet checked how the implementation would be diffucult.

Yeah, I've got some questions regarding this as well. What I have added for cases like this is the '-A' option which reports all NFS mountpoints so that the "correct" one from user POV is included. And subsequently the output could be filtered by a system-specific script that knows how mountpoint is layed out and thus can select appropriate directory that makes sense for the user. Does that make sense?
Regarding filtering the result based on mountpoint ownership - I agree that is useful for some configurations but I'm not yet convinced it belongs into quota(1) as such. But it certainly makes enough sense that I'd merge such a wrapper script with filtering into quota-tools.
