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.
