- 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.rst>.
- 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.
