 autofs-5.1.4 - add master map pseudo options for mount propagation
 From: Ian Kent <raven@themaw.net>
 Add master map entry pseudo mount option of "slave" or "private" to
 allow mount propagation of bind mounts to be set to either "slave" or
 "private".
 This option may be needed when using multi-mounts that have bind mounts
 that bind to a file system that is propagation shared. This is becuase
 the bind mount will have the same properties as its target which causes
 problems for offset mounts. When this happens an unwanted offset mount
 is propagated back to the target file system resulting in a deadlock
 when attempting to access the offset.
 By default bind mounts will inherit the mount propagation of the target
 file system.

 autofs-5.1.4 - add systemd service command line option
 From: Ian Kent <raven@themaw.net>
 When run as a systemd service using the systemd notification method to
 synchronise startup, logging should be done to syslog so the log entry
 format is consistent between daemon and systemd usage.
 So, rather than run use the forground option, add an option to tell
 the automounter it's being run as a systemd service and use syslog
 for logging when its present on the command line.

 autofs-5.1.4 - fix age setting at startup
 From: Ian Kent <raven@themaw.net>
 Commit 2b567ace7d, which resets the master map list on startup
 before retrying a read, incorrectly sets age using time() when
 it should use monotonic_time().
 This causes lookup failures for submounts in cases where a master
 map read retry was needed.
 The failure happens because the mount entry age is greater than
 the map entry age which is meant to indicate the map is no longer
 valid which is not the case.

 autofs-5.1.4 - fix amd parser opts option handling
 From: Ian Kent <raven@themaw.net>
 The recent implementation of the amd map program mount feature
 introduced a regression in the amd parser where only the first
 option of a comma separated list of is applied to a mount entry.

 autofs-5.1.4 - fix update_negative_cache() map source usage
 From: Ian Kent <raven@themaw.net>
 File map sources can be either plain text or executable.
 When the map path is specified without a type (eg. when a
 full path is used) an instance map source is used and the
 original map is left unchanged.
 But update_negative_cache() fails to take this into account
 causing it to update the wrong map cache.
 When a map reload is done the map entry appears to not exist
 so the new map entry is added.
 This could go unnoticed except that, after a map read, the
 map entry cache cleans stale map entries and the existence
 of this negative entry causes the new map entry to be deleted
 and map lookups continue to fail.
 In hindsite the use of an instance map source for this is
 probably uneccessary but changing it will be risky so, for
 now, just make update_negative_cache() use the correct map.

 autofs-5.1.4 - mark removed cache entry negative
 From: Ian Kent <raven@themaw.net>
 When re-reading a map, entries that have been removed are detected
 and deleted from the map entry cache by lookup_prune_cache().
 If a removed map entry is mounted at the time lookup_prune_cache()
 is called the map entry is skipped. This is done becuase the next
 lookup (following the mount expire, which needs the cache entry to
 remain) will detect the stale cache entry and a map update done
 resulting in the stale entry being removed.
 But if a map re-read is performed while the cache entry is mounted
 the cache will appear to up to date so the removed entry will remain
 valid even after it has expired.
 To cover this case it's sufficient to mark the mounted cache entry
 negative during the cache prune which prevents further lookups from
 using the stale entry.

 autofs-5.1.4 - remove autofs4 module load code
 From: Ian Kent <raven@themaw.net>
 The autofs kernel module has finally been renamed from autofs4 to
 autofs so autoloading works so there is no need for manual loading.
 The module load function has been commented out in the source for
 a long time so there should not be any adverse affects from removing
 it.

 autofs-5.1.4 - set bind mount as propagation slave
 From: Ian Kent <raven@themaw.net>
 When using a multi-mount with mount targets that are on the
 local machine and resulting bind mounts are made to a file
 system that is mount propagation shared (such as the root
 file system on systemd managed systems) the autofs offset
 mount triggers made within the bind mount will be propagated
 back to the target file system.
 When this happens the target of the offset (the unwanted
 propagated mount) is itself an autofs trigger mount and
 accessing the path results in a deadlock.
 In order for these multi-mounts to function properly in this
 case bind mounts that contain mount triggers must be set to
 propagation slave or private so the backward propagation
 doesn't occur.

 autofs-5.1.4 - use flags for startup boolean options
 From: Ian Kent <raven@themaw.net>
 The daemon uses a number of boolean flags each stored in unsigned int
 variables. But a single bit flag is sufficient storage for most of
 these flags.
 So use bit flags for these where possible.
