| 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. |
