Saying Y 8*4882a593Smuzhiyun here would allow you to read from their floppies and hard disk 9*4882a593Smuzhiyun partitions. 10*4882a593Smuzhiyun 11*4882a593Smuzhiyun If you have floppies or hard disk partitions like that, it is likely 12*4882a593Smuzhiyun that they contain binaries from those other Unix systems; in order 13*4882a593Smuzhiyun to run these binaries, you will want to install linux-abi which is 14*4882a593Smuzhiyun a set of kernel modules that lets you run SCO, Xenix, Wyse, 15*4882a593Smuzhiyun UnixWare, Dell Unix and System V programs under Linux. It is 16*4882a593Smuzhiyun available via FTP (user: ftp) from 17*4882a593Smuzhiyun <ftp://ftp.openlinux.org/pub/people/hch/linux-abi/>). 18*4882a593Smuzhiyun NOTE: that will work only for binaries from Intel-based systems; 19*4882a593Smuzhiyun PDP ones will have to wait until somebody ports Linux to -11 ;-) 20*4882a593Smuzhiyun 21*4882a593Smuzhiyun If you only intend to mount files from some other Unix over the 22*4882a593Smuzhiyun network using NFS, you don't need the System V file system support 23*4882a593Smuzhiyun (but you need NFS file system support obviously). 24*4882a593Smuzhiyun 25*4882a593Smuzhiyun Note that this option is generally not needed for floppies, since a 26*4882a593Smuzhiyun good portable way to transport files and directories between unixes 27*4882a593Smuzhiyun (and even other operating systems) is given by the tar program ("man 28*4882a593Smuzhiyun tar" or preferably "info tar"). Note also that this option has 29*4882a593Smuzhiyun nothing whatsoever to do with the option "System V IPC". Read about 30*4882a593Smuzhiyun the System V file system in 31*4882a593Smuzhiyun <file:Documentation/filesystems/sysv-fs.rst>. 32*4882a593Smuzhiyun Saying Y here will enlarge your kernel by about 27 KB. 33*4882a593Smuzhiyun 34*4882a593Smuzhiyun To compile this as a module, choose M here: the module will be called 35*4882a593Smuzhiyun sysv. 36*4882a593Smuzhiyun 37*4882a593Smuzhiyun If you haven't heard about all of this before, it's safe to say N. 38
