quotaoff/quotaon stat NFS mountpoints

Binary package hint: quota

Quotaon/quotaoff will not operate on NFS filesystems, stating "Quota cannot be turned on on NFS filesystem". However, the 'stop' action in /etc/init.d/quota calls '/sbin/quotaoff -aug', which stats all NFS mountpoints listed in /etc/mtab. We run krb5 and when the system time is off, the system will hang on shutdown at "turning off quotas." Given that quotas cannot be enabled on NFS filesystems, quotaon/quotaoff should skip stat()ing their mountpoints. Furthermore, as we use the automounter the filesystems in question are not in /etc/fstab so this behavior is inconsistent with the man page which states (for quotaoff):

       -a, --all
              Force all filesystems in /etc/fstab to have their quotas disabled.
