   5          SCO, Xenix and Coherent are commercial Unix systems for Intel
   6          machines, and Version 7 was used on the DEC PDP-11. Saying Y
   7          here would allow you to read from their floppies and hard disk
   8          partitions.
   9
  10          If you have floppies or hard disk partitions like that, it is likely
  11          that they contain binaries from those other Unix systems; in order
  12          to run these binaries, you will want to install linux-abi which is
  13          a set of kernel modules that lets you run SCO, Xenix, Wyse,
  14          UnixWare, Dell Unix and System V programs under Linux.  It is
  15          available via FTP (user: ftp) from
  16          <ftp://ftp.openlinux.org/pub/people/hch/linux-abi/>).
  17          NOTE: that will work only for binaries from Intel-based systems;
  18          PDP ones will have to wait until somebody ports Linux to -11 ;-)
  19
  20          If you only intend to mount files from some other Unix over the
  21          network using NFS, you don't need the System V file system support
  22          (but you need NFS file system support obviously).
  23
  24          Note that this option is generally not needed for floppies, since a
  25          good portable way to transport files and directories between unixes
  26          (and even other operating systems) is given by the tar program ("man
  27          tar" or preferably "info tar").  Note also that this option has
  28          nothing whatsoever to do with the option "System V IPC". Read about
  29          the System V file system in
  30          <file:Documentation/filesystems/sysv-fs.txt>.
  31          Saying Y here will enlarge your kernel by about 27 KB.
  32
  33          To compile this as a module, choose M here: the module will be called
  34          sysv.
  35
  36          If you haven't heard about all of this before, it's safe to say N.
