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

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

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

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

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

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