1 config SYSV_FS 2 tristate "System V/Xenix/V7/Coherent file system support" 3 depends on BLOCK 4 help 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.
