33 | Stores not just filenames but the files themselves in a balanced | |
cc2e2767 | 34 | tree. Uses journalling. |
1da177e4 LT |
35 | |
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.'' | |

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"). | |

483 | The FAT support will enlarge your kernel by about 37 KB. If unsure, |
484 | say Y. | |

487 | fat. Note that if you compile the FAT support as a module, you | |
488 | cannot compile any of the FAT-based file systems into the kernel | |

592 | at the kernel command line when booting the kernel or as an option | |
593 | to insmod when loading the ntfs module. Once the driver is active, | |
594 | you can enable debugging messages by doing (as root): | |

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. | |

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. | |

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), | |

1319 | Sun added support for registering RPC services at an IPv6 | |
1320 | address by creating two new versions of the rpcbind protocol | |
1321 | (RFC 1833). | |
1322 | ||
1323 | This option enables support in the kernel RPC server for | |
1324 | registering kernel RPC services via version 4 of the rpcbind | |
1325 | protocol. If you enable this option, you must run a portmapper | |
1326 | daemon that supports rpcbind protocol version 4. | |
1327 | ||
1328 | Serving NFS over IPv6 from knfsd (the kernel's NFS server) | |

1333 | RPC services using only rpcbind version 2). Distributions | |

1381 | files and printers over local networks. Saying Y here allows you to | |
