          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

          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

          generated by Windows 95 / Windows NT.

          This option will enlarge your kernel by about 7 KB. If unsure,
          answer Y. This will only work if you said Y to "DOS FAT fs support"
          as well. To compile this as a module, choose M here: the module will

          programs from the mtools package.

          The VFAT support enlarges your kernel by about 10 KB and it only

          This is a rewrite from scratch of Linux NTFS support and replaced
          the old NTFS code starting with Linux 2.5.11.  A backport to

          Y here.  This will result in additional consistency checks to be
          performed by the driver as well as additional debugging messages to
          be written to the system log.  Note that debugging messages are
          disabled by default.  To enable them, supply the option debug_msgs=1
          at the kernel command line when booting the kernel or as an option
          to insmod when loading the ntfs module.  Once the driver is active,
          you can enable debugging messages by doing (as root):
          echo 1 > /proc/sys/fs/ntfs-debug
          Replacing the "1" with "0" would disable debug messages.

          If you leave debugging messages disabled, this results in little
          overhead, but enabling debug messages results in very significant
          slowdown of the system.

          This enables the partial, but safe, write support in the NTFS driver.

          The only supported operation is overwriting existing files, without
          changing the file length.  No file or directory creation, deletion or
          renaming is possible.  Note only non-resident files can be written to
          so you may find that some very small files (<500 bytes or so) cannot
          be written to.

          While we cannot guarantee that it will not damage any data, we have
          so far not received a single report where the driver would have
          damaged someones data so we assume it is perfectly safe to use.

          Note:  While write support is safe in this version (a rewrite from
          scratch of the NTFS support), it should be noted that the old NTFS
          write support, included in Linux 2.5.10 and before (since 1997),
          is not safe.

          This is currently useful with TopologiLinux.  TopologiLinux is run
          on top of any DOS/Microsoft Windows system without partitioning your
          hard disk.  Unlike other Linux distributions TopologiLinux does not
          need its own partition.  For more information see

        The sysfs filesystem is a virtual filesystem that the kernel uses to
        export internal kernel objects, their attributes, and their
        relationships to one another.

        Users can use sysfs to ascertain useful information about the running
        kernel, such as the devices the kernel has discovered on each bus and
        which driver each is bound to. sysfs can also be used to tune devices
        and other kernel subsystems.

        Some system agents rely on the information in sysfs to operate.
        /sbin/hotplug uses device and object attributes in sysfs to assist in
        delegating policy decisions, like persistently naming devices.

        sysfs is currently used by the block subsystem to mount the root
        partition.  If sysfs is disabled you must specify the boot device on
        the kernel boot command line via its major and minor numbers.  For

          configfs is a ram-based filesystem that provides the converse
          of sysfs's functionality. Where sysfs is a filesystem-based
          view of kernel objects, configfs is a filesystem-based manager
          of kernel objects, or config_items.

          Both sysfs and configfs can and should exist together on the
          same system. One is not a replacement for the other.

          timestamps.  

          Squashfs is intended for general read-only filesystem use, for
          archival use (i.e. in cases where a .tar.gz file may be used), and in
          embedded systems where low overhead is needed.  Further information

          Some NFS servers support an auxiliary NFSv3 ACL protocol that
          Sun added to Solaris but never became an official part of the
          NFS version 3 protocol.  This protocol extension allows
          applications on NFS clients to manipulate POSIX Access Control
          Lists on files residing on NFS servers.  NFS servers enforce
          ACLs on local files whether this protocol is available or not.

          Choose Y here if your NFS server supports the Solaris NFSv3 ACL
          protocol extension and you want your NFS client to allow
          applications to access and modify ACLs on files on the server.

          Most NFS servers don't support the Solaris NFSv3 ACL protocol
          extension.  You can choose N here or specify the "noacl" mount
          option to prevent your NFS client from trying to use the NFSv3
          ACL protocol.

          (RFC 3530) in the kernel's NFS client.

          To mount NFS servers using NFSv4, you also need to install user

          Below you can choose which versions of the NFS protocol are
          available to clients mounting the NFS server on this system.

          POSIX ACLs on files exported by your system's NFS server.  NFS
          clients which support the Solaris NFSv3 ACL protocol can then
          access and modify ACLs on your NFS server.

          To store ACLs on your NFS server, you also need to enable ACL-

          (RFC 1833).

          This option enables support in the kernel RPC server for
          registering kernel RPC services via version 4 of the rpcbind
          protocol.  If you enable this option, you must run a portmapper
          daemon that supports rpcbind protocol version 4.

          Serving NFS over IPv6 from knfsd (the kernel's NFS server)
          requires that you enable this option and use a portmapper that
          supports rpcbind version 4.

          If unsure, say N to get traditional behavior (register kernel

          transport protocol, and not NetBEUI.  For details, read
          <file:Documentation/filesystems/smbfs.txt> and the SMB-HOWTO,
          available from <http://www.tldp.org/docs.html#howto>.

          Note: if you just want your box to act as an SMB *server* and make
          files and printing services available to Windows clients (which need

          The nls settings can be changed at mount time, if your smbmount

          replication, security model for authentication and encryption,
          persistent client caches and write back caching.
