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,

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.

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.

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.
