Currently, it works for the 13 ext2, ext3, ext4, jfs, ocfs2 and reiserfs file systems. 14 Note that gfs2 and xfs use their own quota system. 15 Ext3, ext4 and reiserfs also support journaled quotas for which 16 you don't need to run quotacheck(8) after an unclean shutdown. 17 For further details, read the Quota mini-HOWTO, available from 18 <https://www.tldp.org/docs.html#howto>, or the documentation provided 19 with the quota tools. Probably the quota support is only useful for 20 multi user systems.
