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

467 If you want to use one of the FAT-based file systems (the MS-DOS and
468 VFAT (Windows 95) file systems), then you must say Y or M here
469 to include FAT support. You will then be able to mount partitions or
470 diskettes with FAT-based file systems and transparently access the
471 files on them, i.e. MSDOS files will look and behave just like all
472 other Unix files.
473
474 This FAT support is not a file system in itself, it only provides
475 the foundation for the other file systems. You will have to say Y or
476 M to at least one of "MSDOS fs support" or "VFAT fs support" in
477 order to make use of it.
478
479 Another way to read and write MSDOS floppies and hard drive
480 partitions from within Linux (but not transparently) is with the
481 mtools ("man mtools") program suite. You don't need to say Y here in
482 order to do that.
483
484 If you need to move large files on floppies between a DOS and a
485 Linux box, say Y here, mount the floppy under Linux with an MSDOS

595 performed by the driver as well as additional debugging messages to
596 be written to the system log. Note that debugging messages are
597 disabled by default. To enable them, supply the option debug_msgs=1
598 at the kernel command line when booting the kernel or as an option
599 to insmod when loading the ntfs module. Once the driver is active,
600 you can enable debugging messages by doing (as root):
601 echo 1 > /proc/sys/fs/ntfs-debug
602 Replacing the "1" with "0" would disable debug messages.
603
604 If you leave debugging messages disabled, this results in little
605 overhead, but enabling debug messages results in very significant

617 The only supported operation is overwriting existing files, without
618 changing the file length. No file or directory creation, deletion or
619 renaming is possible. Note only non-resident files can be written to
620 so you may find that some very small files (<500 bytes or so) cannot
621 be written to.
622
623 While we cannot guarantee that it will not damage any data, we have
624 so far not received a single report where the driver would have
625 damaged someones data so we assume it is perfectly safe to use.
626
627 Note: While write support is safe in this version (a rewrite from
628 scratch of the NTFS support), it should be noted that the old NTFS
629 write support, included in Linux 2.5.10 and before (since 1997),
630 is not safe.

Chuck Leverd24455b2008-02-11 17:11:54 -05001246 Solaris NFS servers support an auxiliary NFSv3 ACL protocol that
1247 never became an official part of the NFS version 3 protocol.
1248 This protocol extension allows applications on NFS clients to
1249 manipulate POSIX Access Control Lists on files residing on NFS
1250 servers. NFS servers enforce POSIX ACLs on local files whether
1251 this protocol is available or not.

1253 This option enables support in your system's NFS server for the
1254 NFSv3 ACL protocol extension allowing NFS clients to manipulate
1255 POSIX ACLs on files exported by your system's NFS server. NFS
1256 clients which support the Solaris NFSv3 ACL protocol can then
1257 access and modify ACLs on your NFS server.
1258
1259 To store ACLs on your NFS server, you also need to enable ACL-
1260 related CONFIG options for your local file systems of choice.

1385 SMB (Server Message Block) is the protocol Windows for Workgroups

1388 mount their file systems (often called "shares" in this context) and
1389 access them just like any other Unix directory. Currently, this
1390 works only if the Windows machines use TCP/IP as the underlying
1391 transport protocol, and not NetBEUI. For details, read
