39 In general, ReiserFS is as fast as ext2, but is very efficient with
40 large directories and small files. Additional patches are needed
41 for NFS and quotas, please see <http://www.namesys.com/> for links.

43 It is more easily extended to have features currently found in
44 database and keyword search systems than block allocation based file
45 systems are. The next version will be so extended, and will support

461 If you want to use one of the FAT-based file systems (the MS-DOS and
462 VFAT (Windows 95) file systems), then you must say Y or M here
463 to include FAT support. You will then be able to mount partitions or
464 diskettes with FAT-based file systems and transparently access the
465 files on them, i.e. MSDOS files will look and behave just like all
466 other Unix files.
467
468 This FAT support is not a file system in itself, it only provides
469 the foundation for the other file systems. You will have to say Y or
470 M to at least one of "MSDOS fs support" or "VFAT fs support" in
471 order to make use of it.
472
473 Another way to read and write MSDOS floppies and hard drive
474 partitions from within Linux (but not transparently) is with the
475 mtools ("man mtools") program suite. You don't need to say Y here in
476 order to do that.
477
478 If you need to move large files on floppies between a DOS and a
479 Linux box, say Y here, mount the floppy under Linux with an MSDOS
480 file system and use GNU tar's M option. GNU tar is a program
481 available for Unix and DOS ("man tar" or "info tar").

Linus Torvalds1da177e2005-04-16 15:20:36 -0700483 The FAT support will enlarge your kernel by about 37 KB. If unsure,

594 you can enable debugging messages by doing (as root):
595 echo 1 > /proc/sys/fs/ntfs-debug
596 Replacing the "1" with "0" would disable debug messages.

612 changing the file length. No file or directory creation, deletion or
613 renaming is possible. Note only non-resident files can be written to
614 so you may find that some very small files (<500 bytes or so) cannot
615 be written to.
616
617 While we cannot guarantee that it will not damage any data, we have
618 so far not received a single report where the driver would have
619 damaged someones data so we assume it is perfectly safe to use.
620
621 Note: While write support is safe in this version (a rewrite from
622 scratch of the NTFS support), it should be noted that the old NTFS
623 write support, included in Linux 2.5.10 and before (since 1997),
624 is not safe.

Chuck Leverd24455b2008-02-11 17:11:54 -05001240 Solaris NFS servers support an auxiliary NFSv3 ACL protocol that
1241 never became an official part of the NFS version 3 protocol.
1242 This protocol extension allows applications on NFS clients to
1243 manipulate POSIX Access Control Lists on files residing on NFS
1244 servers. NFS servers enforce POSIX ACLs on local files whether
1245 this protocol is available or not.
1246
1247 This option enables support in your system's NFS server for the
1248 NFSv3 ACL protocol extension allowing NFS clients to manipulate
1249 POSIX ACLs on files exported by your system's NFS server. NFS
1250 clients which support the Solaris NFSv3 ACL protocol can then
1251 access and modify ACLs on your NFS server.
1252
1253 To store ACLs on your NFS server, you also need to enable ACL-
1254 related CONFIG options for your local file systems of choice.
1255
1256 If unsure, say N.

1379 SMB (Server Message Block) is the protocol Windows for Workgroups

1382 mount their file systems (often called "shares" in this context) and
