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

 25           If you say Y here, quota warnings (about exceeding softlimit, reaching
 26           hardlimit, etc.) will be reported through netlink interface. If unsure,
 27           say Y.

 33         help
 34           If you say Y here, quota warnings (about exceeding softlimit, reaching
 35           hardlimit, etc.) will be printed to the process' controlling terminal.
 36           Note that this behavior is currently deprecated and may go away in
 37           future. Please use notification via netlink socket instead.

 44           If you say Y here, quota subsystem will perform some additional
 45           sanity checks of quota internal structures. If unsure, say N.

 55           This quota format was (is) used by kernels earlier than 2.4.22. If
 56           you have quota working and you don't want to convert to new quota
 57           format say Y here.

 63         help
 64           This config option enables kernel support for vfsv0 and vfsv1 quota
 65           formats. Both these formats support 32-bit UIDs/GIDs and vfsv1 format
 66           also supports 64-bit inode and block quota limits. If you need this
 67           functionality say Y here.
