36 Balanced trees are more efficient than traditional file system
37 architectural foundations.
38
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.
42
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
46 plugins consistent with our motto ``It takes more than a license to
47 make source code open.''

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.

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.

1024 a set of kernel modules that lets you run SCO, Xenix, Wyse,
1025 UnixWare, Dell Unix and System V programs under Linux. It is
1026 available via FTP (user: ftp) from
1027 <ftp://ftp.openlinux.org/pub/people/hch/linux-abi/>).
1028 NOTE: that will work only for binaries from Intel-based systems;
1029 PDP ones will have to wait until somebody ports Linux to -11 ;-)
1030
1031 If you only intend to mount files from some other Unix over the
1032 network using NFS, you don't need the System V file system support
1033 (but you need NFS file system support obviously).
1034
1035 Note that this option is generally not needed for floppies, since a
1036 good portable way to transport files and directories between unixes
1037 (and even other operating systems) is given by the tar program ("man
1038 tar" or preferably "info tar"). Note also that this option has
1039 nothing whatsoever to do with the option "System V IPC". Read about
1040 the System V file system in
1041 <file:Documentation/filesystems/sysv-fs.txt>.
1042 Saying Y here will enlarge your kernel by about 27 KB.
1043
1044 To compile this as a module, choose M here: the module will be called
1045 sysv.

1047 If you haven't heard about all of this before, it's safe to say N.
