Saying Y 962306a36Sopenharmony_ci here would allow you to read from their floppies and hard disk 1062306a36Sopenharmony_ci partitions. 1162306a36Sopenharmony_ci 1262306a36Sopenharmony_ci If you have floppies or hard disk partitions like that, it is likely 1362306a36Sopenharmony_ci that they contain binaries from those other Unix systems; in order 1462306a36Sopenharmony_ci to run these binaries, you will want to install linux-abi which is 1562306a36Sopenharmony_ci a set of kernel modules that lets you run SCO, Xenix, Wyse, 1662306a36Sopenharmony_ci UnixWare, Dell Unix and System V programs under Linux. It is 1762306a36Sopenharmony_ci available via FTP (user: ftp) from 1862306a36Sopenharmony_ci <ftp://ftp.openlinux.org/pub/people/hch/linux-abi/>). 1962306a36Sopenharmony_ci NOTE: that will work only for binaries from Intel-based systems; 2062306a36Sopenharmony_ci PDP ones will have to wait until somebody ports Linux to -11 ;-) 2162306a36Sopenharmony_ci 2262306a36Sopenharmony_ci If you only intend to mount files from some other Unix over the 2362306a36Sopenharmony_ci network using NFS, you don't need the System V file system support 2462306a36Sopenharmony_ci (but you need NFS file system support obviously). 2562306a36Sopenharmony_ci 2662306a36Sopenharmony_ci Note that this option is generally not needed for floppies, since a 2762306a36Sopenharmony_ci good portable way to transport files and directories between unixes 2862306a36Sopenharmony_ci (and even other operating systems) is given by the tar program ("man 2962306a36Sopenharmony_ci tar" or preferably "info tar"). Note also that this option has 3062306a36Sopenharmony_ci nothing whatsoever to do with the option "System V IPC". Read about 3162306a36Sopenharmony_ci the System V file system in 3262306a36Sopenharmony_ci <file:Documentation/filesystems/sysv-fs.rst>. 3362306a36Sopenharmony_ci Saying Y here will enlarge your kernel by about 27 KB. 3462306a36Sopenharmony_ci 3562306a36Sopenharmony_ci To compile this as a module, choose M here: the module will be called 3662306a36Sopenharmony_ci sysv. 3762306a36Sopenharmony_ci 3862306a36Sopenharmony_ci If you haven't heard about all of this before, it's safe to say N. 39
