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

If you say Y here, quota warnings (about exceeding softlimit, reaching

hardlimit, etc.) will be reported through netlink interface. If unsure,

say Y.

help
|

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

This quota format was (is) used by kernels earlier than 2.4.22. If
|

you have quota working and you don't want to convert to new quota
|

format say Y here.

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