0010 help
0011 If you say Y here, you will be able to set per user limits for disk
0012 usage (also called disk quotas). Currently, it works for the
0013 ext2, ext3, ext4, jfs, ocfs2 and reiserfs file systems.
0014 Note that gfs2 and xfs use their own quota system.
0015 Ext3, ext4 and reiserfs also support journaled quotas for which
0016 you don't need to run quotacheck(8) after an unclean shutdown.
0017 For further details, read the Quota mini-HOWTO, available from
0018 <https://www.tldp.org/docs.html#howto>, or the documentation provided
0019 with the quota tools. Probably the quota support is only useful for
0020 multi user systems. If unsure, say N.

0026 If you say Y here, quota warnings (about exceeding softlimit, reaching
0027 hardlimit, etc.) will be reported through netlink interface. If unsure,

0034 help
0035 If you say Y here, quota warnings (about exceeding softlimit, reaching
0036 hardlimit, etc.) will be printed to the process' controlling terminal.
0037 Note that this behavior is currently deprecated and may go away in
0038 future. Please use notification via netlink socket instead.

0056 This quota format was (is) used by kernels earlier than 2.4.22. If
0057 you have quota working and you don't want to convert to new quota
0058 format say Y here.

0065 This config option enables kernel support for vfsv0 and vfsv1 quota
0066 formats. Both these formats support 32-bit UIDs/GIDs and vfsv1 format
0067 also supports 64-bit inode and block quota limits. If you need this
0068 functionality say Y here.
