Saying Y 98af915baSAlexey Dobriyan here would allow you to read from their floppies and hard disk 108af915baSAlexey Dobriyan partitions. 118af915baSAlexey Dobriyan 128af915baSAlexey Dobriyan If you have floppies or hard disk partitions like that, it is likely 138af915baSAlexey Dobriyan that they contain binaries from those other Unix systems; in order 148af915baSAlexey Dobriyan to run these binaries, you will want to install linux-abi which is 158af915baSAlexey Dobriyan a set of kernel modules that lets you run SCO, Xenix, Wyse, 168af915baSAlexey Dobriyan UnixWare, Dell Unix and System V programs under Linux. It is 178af915baSAlexey Dobriyan available via FTP (user: ftp) from 188af915baSAlexey Dobriyan <ftp://ftp.openlinux.org/pub/people/hch/linux-abi/>). 198af915baSAlexey Dobriyan NOTE: that will work only for binaries from Intel-based systems; 208af915baSAlexey Dobriyan PDP ones will have to wait until somebody ports Linux to -11 ;-) 218af915baSAlexey Dobriyan 228af915baSAlexey Dobriyan If you only intend to mount files from some other Unix over the 238af915baSAlexey Dobriyan network using NFS, you don't need the System V file system support 248af915baSAlexey Dobriyan (but you need NFS file system support obviously). 258af915baSAlexey Dobriyan 268af915baSAlexey Dobriyan Note that this option is generally not needed for floppies, since a 278af915baSAlexey Dobriyan good portable way to transport files and directories between unixes 288af915baSAlexey Dobriyan (and even other operating systems) is given by the tar program ("man 298af915baSAlexey Dobriyan tar" or preferably "info tar"). Note also that this option has 308af915baSAlexey Dobriyan nothing whatsoever to do with the option "System V IPC".
