Yes, this is true.  To be 100% accurate, one would say that
"repquota [for XFS] returns only those UIDs returned from the
getpwent(3) function" - since getpwent will also lookup passwd
entries via NIS if configured, it is not quite true to say that
it _only_ looks in /etc/passwd.

All of the above is also true on IRIX.  It seems the original
author had considered this problem, and in IRIX left a place-
holder quotactl command "Q_BULKQSTAT" which I imagine would,
had it been implemented, have been able to walk through quota
files on XFS without needing this getpwent crutch.

Would be an interesting little project to implement this for
XFS on Linux if you're interested... just a simple matter of
programming.  Another fix would be to use something like NIS
to ensure the uid:name mapping is available to the server.

cheers.
