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