config QUOTA
	bool "Quota support"
	help
	  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, and reiserfs file system. ext3 also supports journalled
	  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
	  <http://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.

config QUOTA_NETLINK_INTERFACE
	bool "Report quota messages through netlink interface"
	depends on QUOTA && NET
	help
	  If you say Y here, quota warnings (about exceeding softlimit, reaching
	  hardlimit, etc.) will be reported through netlink interface. If unsure,
	  say Y.

config PRINT_QUOTA_WARNING

	depends on QUOTA
	default 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.

config FAT_FS
	tristate
	select NLS
	help
	  If you want to use one of the FAT-based file systems (the MS-DOS and
	  VFAT (Windows 95) file systems), then you must say Y or M here
	  to include FAT support. You will then be able to mount partitions or
	  diskettes with FAT-based file systems and transparently access the
	  files on them, i.e. MSDOS files will look and behave just like all
	  other Unix files.

	  This FAT support is not a file system in itself, it only provides
	  the foundation for the other file systems. You will have to say Y or
	  M to at least one of "MSDOS fs support" or "VFAT fs support" in
	  order to make use of it.

	  Another way to read and write MSDOS floppies and hard drive
	  partitions from within Linux (but not transparently) is with the
	  mtools ("man mtools") program suite. You don't need to say Y here in
	  order to do that.

	  If you need to move large files on floppies between a DOS and a
	  Linux box, say Y here, mount the floppy under Linux with an MSDOS
	  file system and use GNU tar's M option. GNU tar is a program
	  available for Unix and DOS ("man tar" or "info tar").

	  The FAT support will enlarge your kernel by about 37 KB. If unsure,
	  say Y.

	  To compile this as a module, choose M here: the module will be called
	  fat.  Note that if you compile the FAT support as a module, you
	  cannot compile any of the FAT-based file systems into the kernel
	  -- they will have to be modules as well.

config MSDOS_FS
	tristate "MSDOS fs support"
	select FAT_FS
	help
	  This allows you to mount MSDOS partitions of your hard drive (unless
	  they are compressed; to access compressed MSDOS partitions under
	  Linux, you can either use the DOS emulator DOSEMU, described in the
	  DOSEMU-HOWTO, available from
	  <http://www.tldp.org/docs.html#howto>, or try dmsdosfs in
	  <ftp://ibiblio.org/pub/Linux/system/filesystems/dosfs/>. If you
	  intend to use dosemu with a non-compressed MSDOS partition, say Y
	  here) and MSDOS floppies. This means that file access becomes
	  transparent, i.e. the MSDOS files look and behave just like all
	  other Unix files.

	  If you have Windows 95 or Windows NT installed on your MSDOS
	  partitions, you should use the VFAT file system (say Y to "VFAT fs
	  support" below), or you will not be able
