One should be able to enable quota enforcement using quotaon /home or
quotaon -a.  These commands fail when run on rc2.



Reproducible: Always
Steps to Reproduce:
1.  Install system with separate /home filesystem
2.  Edit /etc/fstab, replace "defaults"  with "usrquota"
3.  mount -o remount /home
4.  Verify that /home is mounted as quota-capable: mount
5.  Run quotacheck /home to create /home/quota.user
6.  quotaon /home (it fails)
7.  edquota <some user>, set a limit
8.  repquota /home or quota <some user> should show quotas (so it really
did fail)

Actual Results:  [root@station5 /root]# quotaon -a
quotaon: using /home/quota.user on /dev/hda7: Invalid argument


Expected Results:  successful completion of quotaon;
ability to assign quotas
