[patch] DUID in fstab(5) breaks quota(1) reporting

[Dimitri Sokolyuk]

Synopsis:       DUID in fstab(5) breaks quota(1) reporting
Category:       system
Environment:

        System      : OpenBSD 5.2
        Details     : OpenBSD 5.2 (GENERIC.MP) #368: Wed Aug  1 10:04:49 MDT 
2012
                         
dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP

        Architecture: OpenBSD.amd64
        Machine     : amd64

Description:

        If DUIDs are uses in fstab(5) (as it is default now), quota(5)
        will report none information at all.

How-To-Repeat:

        Setup user quota as described in FAQ 10.11
        Run quota. It will print "none" in all circumstances for all users.

Fix:

        Use getfsfile(3) istead of getfsspec(3) to lookup fstab entries.
