33 | Stores not just filenames but the files themselves in a balanced | |

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.'' | |

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

597 | to insmod when loading the ntfs module. Once the driver is active, | |
598 | you can enable debugging messages by doing (as root): | |

619 | be written to. | |

621 | While we cannot guarantee that it will not damage any data, we have | |
622 | so far not received a single report where the driver would have | |

625 | Note: While write support is safe in this version (a rewrite from | |
626 | scratch of the NTFS support), it should be noted that the old NTFS | |
627 | write support, included in Linux 2.5.10 and before (since 1997), | |

1323 | Sun added support for registering RPC services at an IPv6 | |
1324 | address by creating two new versions of the rpcbind protocol | |
1325 | (RFC 1833). | |
1326 | ||
1327 | This option enables support in the kernel RPC server for | |
1328 | registering kernel RPC services via version 4 of the rpcbind | |

1385 | files and printers over local networks. Saying Y here allows you to | |
