+Apart from the old quota system (as in ext2, jqfmt=vfsold aka version 1 quota)
+ext3 also supports journaled quotas (version 2 quota). jqfmt=vfsv0
+enables journaled quotas. For journaled quotas the mount options
+usrjquot=aquota.user and grpjquota=aquota.group are required to tell the
+quota system which quota database files to use. Journaled quotas have the
+advantage that even after a crash no quota check is required.
