Saying Y9 here would allow you to read from their floppies and hard disk10 partitions.11 12 If you have floppies or hard disk partitions like that, it is likely13 that they contain binaries from those other Unix systems; in order14 to run these binaries, you will want to install linux-abi which is15 a set of kernel modules that lets you run SCO, Xenix, Wyse,16 UnixWare, Dell Unix and System V programs under Linux. It is17 available via FTP (user: ftp) from18 <ftp://ftp.openlinux.org/pub/people/hch/linux-abi/>).19 NOTE: that will work only for binaries from Intel-based systems;20 PDP ones will have to wait until somebody ports Linux to -11 ;-)21 22 If you only intend to mount files from some other Unix over the23 network using NFS, you don't need the System V file system support24 (but you need NFS file system support obviously).25 26 Note that this option is generally not needed for floppies, since a27 good portable way to transport files and directories between unixes28 (and even other operating systems) is given by the tar program ("man29 tar" or preferably "info tar"). Note also that this option has30 nothing whatsoever to do with the option "System V IPC". Read about31 the System V file system in32 <file:Documentation/filesystems/sysv-fs.rst>.33 Saying Y here will enlarge your kernel by about 27 KB.34 35 To compile this as a module, choose M here: the module will be called36 sysv.37 38 If you haven't heard about all of this before, it's safe to say N.39
