Saying Y 88c2ecf20Sopenharmony_ci here would allow you to read from their floppies and hard disk 98c2ecf20Sopenharmony_ci partitions. 108c2ecf20Sopenharmony_ci 118c2ecf20Sopenharmony_ci If you have floppies or hard disk partitions like that, it is likely 128c2ecf20Sopenharmony_ci that they contain binaries from those other Unix systems; in order 138c2ecf20Sopenharmony_ci to run these binaries, you will want to install linux-abi which is 148c2ecf20Sopenharmony_ci a set of kernel modules that lets you run SCO, Xenix, Wyse, 158c2ecf20Sopenharmony_ci UnixWare, Dell Unix and System V programs under Linux. It is 168c2ecf20Sopenharmony_ci available via FTP (user: ftp) from 178c2ecf20Sopenharmony_ci <ftp://ftp.openlinux.org/pub/people/hch/linux-abi/>). 188c2ecf20Sopenharmony_ci NOTE: that will work only for binaries from Intel-based systems; 198c2ecf20Sopenharmony_ci PDP ones will have to wait until somebody ports Linux to -11 ;-) 208c2ecf20Sopenharmony_ci 218c2ecf20Sopenharmony_ci If you only intend to mount files from some other Unix over the 228c2ecf20Sopenharmony_ci network using NFS, you don't need the System V file system support 238c2ecf20Sopenharmony_ci (but you need NFS file system support obviously). 248c2ecf20Sopenharmony_ci 258c2ecf20Sopenharmony_ci Note that this option is generally not needed for floppies, since a 268c2ecf20Sopenharmony_ci good portable way to transport files and directories between unixes 278c2ecf20Sopenharmony_ci (and even other operating systems) is given by the tar program ("man 288c2ecf20Sopenharmony_ci tar" or preferably "info tar"). Note also that this option has 298c2ecf20Sopenharmony_ci nothing whatsoever to do with the option "System V IPC". Read about 308c2ecf20Sopenharmony_ci the System V file system in 318c2ecf20Sopenharmony_ci <file:Documentation/filesystems/sysv-fs.rst>. 328c2ecf20Sopenharmony_ci Saying Y here will enlarge your kernel by about 27 KB. 338c2ecf20Sopenharmony_ci 348c2ecf20Sopenharmony_ci To compile this as a module, choose M here: the module will be called 358c2ecf20Sopenharmony_ci sysv. 368c2ecf20Sopenharmony_ci 378c2ecf20Sopenharmony_ci If you haven't heard about all of this before, it's safe to say N. 38
