34
35 Balanced trees are more efficient than traditional file system
36 architectural foundations.
37
38 In general, ReiserFS is as fast as ext2, but is very efficient with
39 large directories and small files. Additional patches are needed
40 for NFS and quotas, please see <http://www.namesys.com/> for links.
41
42 It is more easily extended to have features currently found in
43 database and keyword search systems than block allocation based file
44 systems are. The next version will be so extended, and will support
45 plugins consistent with our motto ``It takes more than a license to
46 make source code open.''

630 you can enable debugging messages by doing (as root):

647 The only supported operation is overwriting existing files, without
648 changing the file length. No file or directory creation, deletion or
649 renaming is possible. Note only non-resident files can be written to
650 so you may find that some very small files (<500 bytes or so) cannot
651 be written to.
652
653 While we cannot guarantee that it will not damage any data, we have
654 so far not received a single report where the driver would have
655 damaged someones data so we assume it is perfectly safe to use.
656
657 Note: While write support is safe in this version (a rewrite from
658 scratch of the NTFS support), it should be noted that the old NTFS
659 write support, included in Linux 2.5.10 and before (since 1997),

1494 help
1495 Coda is an advanced network file system, similar to NFS in that it
1496 enables you to mount file systems of a remote server and access them
1497 with regular Unix commands as if they were sitting on your hard
1498 disk. Coda has several advantages over NFS: support for
1499 disconnected operation (e.g. for laptops), read/write server
1500 replication, security model for authentication and encryption,
1501 persistent client caches and write back caching.
1502
1503 If you say Y here, your Linux box will be able to act as a Coda
1504 *client*. You will need user level code as well, both for the
1505 client and server. Servers are currently user level, i.e. they need
1506 no kernel support. Please read
1507 <file:Documentation/filesystems/coda.txt> and check out the Coda
1508 home page <http://www.coda.cs.cmu.edu/>.
1509
1510 To compile the coda client support as a module, choose M here: the
1511 module will be called coda.
