quota			These options are ignored by the filesystem. They

noquota			are used only by quota tools to recognize volumes

usrquota		in the quota-tools package for more details

jqfmt=<quota type>	These options tell filesystem details about quota

usrjquota=<file>	so that quota information can be properly updated
