Currently, it works for the 12 ext2, ext3, ext4, f2fs, jfs and ocfs2 file systems. Note that gfs2 13 and xfs use their own quota system. Ext3 and ext4 also support 14 journaled quotas for which you don't need to run quotacheck(8) after 15 an unclean shutdown. For further details, read the Quota mini-HOWTO, 16 available from <https://www.tldp.org/docs.html#howto>, or the 17 documentation provided with the quota tools. Probably the quota 18 support is only useful for multi user systems.
