Hi all, It's time for a new release, autofs-5.1.3. Of particular interest is the addition browse support for amd format maps. The browsable_dirs configuration option can be set to either "yes" or "no" and the pseudo option "browsable" can be used as an option of mount type "auto" mounts. Note that the browsable_dirs "full" option and the mount type auto "fullybrowsabe" option, mostly used for map debugging, cannot be provided by autofs. Related changes are the removal of the requirement to include entries for amd format maps in the master map. The optional amd format map mount sections may be used without adding these entries, in the same way these sections are used in the amd configuration. This prevents the need to include potentially incompatible entries in shared master maps in multi-vendor environments. Something to watch out for is that autofs is no longer tolerant of misconfigured nsswitch "automount:" entries. If nsswitch sources that aren't configured are present it can lead to an unconditional 10 second delay at startup with some unexpected log errors. autofs is probably not going to interfere with nsswitch.conf because it is not the owner of the file so it needs to be set correctly by people using autofs. This will often mean just removing the inappropriate "nisplus" source present in the default installed nsswitch.conf. There's two added configuration parameters which hopefully will help with map source availability problems at startup. The "master_wait" configuration option (default 10 seconds) will retry reading the master map for the configured time when certain errors are encountered (the reason misconfigured nsswitch configurations cause a delay). And the option "sss_master_map_wait" (default 0, disabled) has been added specifically for the sss source. This option may be needed because the error returned when sss is not yet available to answer queries can't be distinguished from a real "map does not exist" return. The default of disabled is because the sss source not being ready problem has already be resolved in recent versions of sss itself. Additionally there a number of bug fixes and small improvements. autofs ====== The package can be found at: https://www.kernel.org/pub/linux/daemons/autofs/v5/ It is autofs-5.1.3.tar.[gz|xz] No source rpm is there as it can be produced by using: rpmbuild -ts autofs-5.1.3.tar.gz and the binary rpm by using: rpmbuild -tb autofs-5.1.3.tar.gz See the README.amd-maps file for information about using amd format maps.
