+ tristate "System V/Xenix/V7/Coherent file system support"
+ depends on BLOCK
+ help
+ SCO, Xenix and Coherent are commercial Unix systems for Intel
+ machines, and Version 7 was used on the DEC PDP-11. Saying Y
+ here would allow you to read from their floppies and hard disk
+ partitions.
+
+ If you have floppies or hard disk partitions like that, it is likely
+ that they contain binaries from those other Unix systems; in order
+ to run these binaries, you will want to install linux-abi which is
+ a set of kernel modules that lets you run SCO, Xenix, Wyse,
+ UnixWare, Dell Unix and System V programs under Linux. It is
+ available via FTP (user: ftp) from
+ <ftp://ftp.openlinux.org/pub/people/hch/linux-abi/>).
+ NOTE: that will work only for binaries from Intel-based systems;
+ PDP ones will have to wait until somebody ports Linux to -11 ;-)
+
+ If you only intend to mount files from some other Unix over the
+ network using NFS, you don't need the System V file system support
+ (but you need NFS file system support obviously).
+
+ Note that this option is generally not needed for floppies, since a
+ good portable way to transport files and directories between unixes
+ (and even other operating systems) is given by the tar program ("man
+ tar" or preferably "info tar"). Note also that this option has
+ nothing whatsoever to do with the option "System V IPC". Read about
+ the System V file system in
+ <file:Documentation/filesystems/sysv-fs.txt>.
+ Saying Y here will enlarge your kernel by about 27 KB.
+
+ To compile this as a module, choose M here: the module will be called
+ sysv.
+
+ If you haven't heard about all of this before, it's safe to say N.
