autofs-5.0.0 ============ Differences between version 4 and version 5. - Master map is now read and parsed by the `automount' daemon - the parameters for the `automount' daemon are now very different. See automount(8). - The master map default is "auto.master" and nsswitch is used to locate it. The line "+auto.master" has been added to the default installed "/etc/auto.master" to ensure that those using NIS will still find their master map. This is in line with other industry automount implementations. The name of the default master map can be overridden by setting the MASTER_MAP_NAME configuration variable. - The `automount' daemon is now a multi-threaded application and so appears as a single process (unless a thread process display option is used). - `autofs' filesystem mounts only appear in /proc/mounts and not /etc/mtab. If you have a large number of entries in a direct mount map and link /etc/mtab to /proc/mounts you may see performance degradation. - `autofs' version 5.0.0 will refuse to run if it cannot find an autofs4 kernel module that supports protocol version 5.00 or above. - mount options present in the master map are accumulated by default which is different to the behavior of some other autofs implementations. A configuration option is available to change this behavior if required. New in 5.0.0 is: - improved direct mount map support - single level map entries now work as expected. - top level directory of direct mount hierarchy no longer obscures directory tree below. - `+' map inclusion - maps preceded by a `+' in file maps may now be included inline. - implemented for the master map and mount maps. - added nsswitch map source support - is now used to locate maps if no map source is given in their specification. - is used for both master map and mount maps. - rewrote multi-mount map code - multi-mount map entry offsets now mount and expire independently instead of having to mount and umount all offset entries at once. - added LDAP encryption and authentication support - needs to be enabled using a configure option. - a configuration file specifies whether encryption and authentication is to be used (see INSTALL and auto.master(5) for more information). - improved shutdown and restart - needs to be enabled using a configure option. - see INSTALL for more information. - a "hosts" map module has been added - an entry like "/net -hosts" is now understood and uses the new multi-mount semantics for lazy mount/umount of exports from the host. - the implementation is quite simple minded at this stage and will need refinement. It just iterates through the host table and adds any host names it finds to the internal map. Things not yet done =================== - I have no way to test the Gentoo setup here anymore so it is unlikely to work. Patches from anyone who needs this are welcome. Ian
