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.''

597 Y here. This will result in additional consistency checks to be
598 performed by the driver as well as additional debugging messages to
599 be written to the system log. Note that debugging messages are
600 disabled by default. To enable them, supply the option debug_msgs=1
601 at the kernel command line when booting the kernel or as an option
602 to insmod when loading the ntfs module. Once the driver is active,
603 you can enable debugging messages by doing (as root):
604 echo 1 > /proc/sys/fs/ntfs-debug
605 Replacing the "1" with "0" would disable debug messages.

618 This enables the partial, but safe, write support in the NTFS driver.

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

1027 a set of kernel modules that lets you run SCO, Xenix, Wyse,
1028 UnixWare, Dell Unix and System V programs under Linux. It is
1029 available via FTP (user: ftp) from
1030 <ftp://ftp.openlinux.org/pub/people/hch/linux-abi/>).
1031 NOTE: that will work only for binaries from Intel-based systems;
1032 PDP ones will have to wait until somebody ports Linux to -11 ;-)
1033
1034 If you only intend to mount files from some other Unix over the
1035 network using NFS, you don't need the System V file system support
1036 (but you need NFS file system support obviously).
1037
1038 Note that this option is generally not needed for floppies, since a
1039 good portable way to transport files and directories between unixes
1040 (and even other operating systems) is given by the tar program ("man
1041 tar" or preferably "info tar"). Note also that this option has
1042 nothing whatsoever to do with the option "System V IPC". Read about
1043 the System V file system in
1044 <file:Documentation/filesystems/sysv-fs.txt>.
1045 Saying Y here will enlarge your kernel by about 27 KB.
1046
1047 To compile this as a module, choose M here: the module will be called
1048 sysv.
