222 Saying Y here includes support for SquashFS 4.0 (a Compressed
223 Read-Only File System). Squashfs is a highly compressed read-only
224 filesystem for Linux. It uses zlib compression to compress both
225 files, inodes and directories. Inodes in the system are very small
226 and all blocks are packed to minimise data overhead. Block sizes
227 greater than 4K are supported up to a maximum of 1 Mbytes (default
228 block size 128K). SquashFS 4.0 supports 64 bit filesystems and files
229 (larger than 4GB), full uid/gid information, hard links and
230 timestamps.
231
232 Squashfs is intended for general read-only filesystem use, for
233 archival use (i.e. in cases where a .tar.gz file may be used), and in
234 embedded systems where low overhead is needed. Further information
235 and tools are available from http://squashfs.sourceforge.net.

382 SCO, Xenix and Coherent are commercial Unix systems for Intel
383 machines, and Version 7 was used on the DEC PDP-11. Saying Y
384 here would allow you to read from their floppies and hard disk
385 partitions.
386
387 If you have floppies or hard disk partitions like that, it is likely
388 that they contain binaries from those other Unix systems; in order
Matt LaPlantecab00892006-10-03 22:36:44 +0200389 to run these binaries, you will want to install linux-abi which is
Linus Torvalds1da177e2005-04-16 15:20:36 -0700390 a set of kernel modules that lets you run SCO, Xenix, Wyse,
391 UnixWare, Dell Unix and System V programs under Linux. It is
392 available via FTP (user: ftp) from
393 <ftp://ftp.openlinux.org/pub/people/hch/linux-abi/>).
394 NOTE: that will work only for binaries from Intel-based systems;
395 PDP ones will have to wait until somebody ports Linux to -11 ;-)
396
397 If you only intend to mount files from some other Unix over the
398 network using NFS, you don't need the System V file system support
399 (but you need NFS file system support obviously).
400
401 Note that this option is generally not needed for floppies, since a
402 good portable way to transport files and directories between unixes
403 (and even other operating systems) is given by the tar program ("man
404 tar" or preferably "info tar"). Note also that this option has
405 nothing whatsoever to do with the option "System V IPC". Read about
406 the System V file system in
407 <file:Documentation/filesystems/sysv-fs.txt>.
408 Saying Y here will enlarge your kernel by about 27 KB.

410 To compile this as a module, choose M here: the module will be called
411 sysv.

751 SMB (Server Message Block) is the protocol Windows for Workgroups
752 (WfW), Windows 95/98, Windows NT and OS/2 Lan Manager use to share
753 files and printers over local networks. Saying Y here allows you to
754 mount their file systems (often called "shares" in this context) and
755 access them just like any other Unix directory. Currently, this
756 works only if the Windows machines use TCP/IP as the underlying
757 transport protocol, and not NetBEUI. For details, read
758 <file:Documentation/filesystems/smbfs.txt> and the SMB-HOWTO,
759 available from <http://www.tldp.org/docs.html#howto>.
760
761 Note: if you just want your box to act as an SMB *server* and make
762 files and printing services available to Windows clients (which need
763 to have a TCP/IP stack), you don't need to say Y here; you can use
764 the program SAMBA (available from <ftp://ftp.samba.org/pub/samba/>)
765 for that.

782 The nls settings can be changed at mount time, if your smbmount

808 NCP (NetWare Core Protocol) is a protocol that runs over IPX and is

810 IPX what NFS is to TCP/IP, if that helps. Saying Y here allows you
811 to mount NetWare file server volumes and to access them just like
812 any other Unix directory. For details, please read the file

830 help
831 Coda is an advanced network file system, similar to NFS in that it
832 enables you to mount file systems of a remote server and access them
833 with regular Unix commands as if they were sitting on your hard
834 disk. Coda has several advantages over NFS: support for
835 disconnected operation (e.g. for laptops), read/write server
836 replication, security model for authentication and encryption,
837 persistent client caches and write back caching.
838
839 If you say Y here, your Linux box will be able to act as a Coda
840 *client*. You will need user level code as well, both for the
841 client and server. Servers are currently user level, i.e. they need
842 no kernel support. Please read
