NAME

DESCRIPTION

No checks are performed on these settings, it is the responsibility of the system administrator to create a working configuration. For many systems the defaults ought to be fine and a configuration file is not required at all.

TOOL LOCATIONS

AMD SETTINGS

Unless noted otherwise after changing any of these settings automounter has to be restarted. Failing to do so can result in an inconsistent state.

amd="/usr/sbin/amd"

The location of the automounter daemon amd(8).

amq="/usr/sbin/amq"

The location of the automounter query tool amq(8).

a="/var/run/automounter.amd"

 

c=4

 

w=2

 

l="/var/run/automounter.amd.log"

 

directory="/var/run/automounter.amd.mnt"

 

map="/var/run/automounter.amd.map"

This is the location of the dynamically created map.

pidfile="/var/run/automounter.amd.pid"

The PID file for amd(8). Changing this will break the rc(8) script.

static_map="/etc/amd.map"

The map file that will be used to build the dynamic map from.

For this setting to take effect an update call is sufficient.

RPC SETTINGS

rpcbind="/usr/sbin/rpcbind"

The location of the RPC daemon rpcbind(8).

rpcinfo="/usr/bin/rpcinfo"

The location of the RPC reporting tool rpcinfo(8).

RUNTIME SETTINGS

blacklist_devs

This variable can be used to exclude devices from automounting. The devices are Shell-Patterns separated by ','.

The following example excludes ATA disks and CD-/DVD-drives:

blacklist_devs="ad*,acd*"
    

Changing blacklist_devs takes effect after an update call.

blacklist_nodes

This allows blacklisting by mount names. Like blacklist_devs it is a ',' separated list of Shell-Patterns. The following example blacklists all ufs partitions:

blacklist_nodes="ufs/*"
    

Changing blacklist_nodes takes effect after an update call.

detect_glabel=1

If set to 0 or any other value not 1, discovering file systems through the geom label class is deactivated.

This setting takes effect with the next update call, excepting already mounted file systems.

detect_iso9660=1

If set to 0 or any other value not 1, assuming that devices matching the iso9660_devs pattern are optical disk drives is turned off.

This setting takes effect with the next update call, excepting already mounted file systems.

detect_probe=1

If set to 0 or any other value not 1, discovering file systems through probing is deactivated.

This setting takes effect with the next update call, excepting already mounted file systems.

devfs="/dev"

The location of the devfs(5). This is required to know where to find the mount device nodes.

This setting takes immediate effect.

evil_fuse=0

Setting this to 1 will activate a bug workaround for fuse based file systems such as ntfs-3g from the sysutils/fusefs-ntfs port. Fuse closes all opened files when an unmount is attempted. With automounter this happens every five seconds by default.

The workaround uses fstat(1) to check whether files are opened on fuse based file systems and prevents the unmount command from being run if this is the case. The downside is that fstat is not able to see on which fuse file system the file is opened. So all fuse file systems remain mounted until there are no more opened files on any of them.

As long as only one fuse based file system is in use there are no downsides to using this workaround.

The workaround takes immediate effect.

iso9660=cd9660

This is obligatory to mount optical discs.

This setting takes immediate effect.

iso9660_devs="acd*,cd*"

This is a comma separated list of glob patterns. Devices matching one of the patterns are assumed to be optical disk drives.

Changes to this setting take effect with the next update call.

iso9660_options=ro

This is more appropriate for optical devices than the default mount options.

This setting takes immediate effect.

linkdir="/media"

The directory that will be populated with the links to amd(8) mounts. It might be good to change this to avoid clashes with hald(8) based mounting solutions.

It is recommended to stop automounter before changing this setting, because a change would prevent automounter from cleaning up properly behind itself.

lock="/var/run/automounter.lock"

A lock file that is used to prevent clashes between several instances of automounter(8), e.g. when there are several USB events at once.

This takes immediate effect.

logger="/usr/bin/logger -st automounter"

The logger(1) command, reports messages to syslogd(8). This can be replaced with an arbitrary command that accepts messages as arguments and from stdin(4).

Changes take immediate effect.

mount_options=rw,noatime,noexec

These are the default options given to mount when mounting a file system.

This takes immediate effect.

mountdir="/var/run/automounter.mnt"

A directory where automounter(8) will create the mount points for amd.

Like with linkdir it is required to stop automounter before changing mountdir to avoid an inconsistent state.

nodes="/var/tmp/automounter.nodes"

This file is used to remember which mounts are currently managed by automounter(8).

It is required to stop automounter before changing nodes.

oldnodes="/tmp/automounter.nodes.old"

A temporary file that is used to find out weather any mounts should be cleaned up.

A change of oldnodes takes immediate effect.

probe="/tmp/automounter.probe"

A directory used for mount attempts to probe file system types of unlabeled geom providers.

Changing this takes immediate effect.

probed="/tmp/automounter.probed"

A temporary file used to prevent the probing of geom providers whose labels have been blacklisted.

Changing this takes immediate effect.

screen="/tmp/automounter.screen"

A file with a list of devices present for the last update. Unless the file modification time is further in the past than the time specified by timeout, or the current device list differs, devd(8) issued update calls are discarded.

The device discovery activities of automounter may cause new devd events. This mechanism effectively prevents race conditions.

Changing this takes immediate effect.

probe_types=ufs,msdosfs,iso9660,ntfs,ext2fs

A comma separated list of file system types to automatically probe for.

Changing probe_types takes effect with the next update call.

timeout=10

The time out for acquiring the lock. If the time out passes without gaining the lock the instance of automounter(8) is skipped.

Changing the timeout takes immediate effect.

FILE SYSTEM SPECIFIC SETTINGS

The parameter -t defaults to the identified file system type. For optical drives the file system type does not match the mount type, hence iso9660=cd9660 is set by default. All mount types can be set similarly. The following example shows how to use ntfs-3g to mount ntfs file systems.

ntfs=ntfs-3g

The parameter -o defaults to mount_options, but it can be set individually for each file system type. The following example will mount msdosfs file systems with UTF-8 encoded file names:

msdosfs_options=$mount_options,-L=en_GB.UTF-8

Changing these settings takes immediate effect.

Note that more recent versions of FreeBSD have the mountprog option, which makes the -t parameter obsolete in most cases. Read mount(8) for details.

GELI

New images and keys can be added any time. Images should not be removed while mounted.

geli=0

By default all geli features are deactivated. To enable them this should be set to 1.

geli_nodes="/var/run/automounter.geli.nodes"

A file that is used to remember the device as which images were attached and the key that was used for attaching.

geli_oldnodes="/tmp/automounter.geli.oldnodes"

A temporary file that is used when removing stale attachments or adding new ones.

geli_availablekeys="/var/run/automounter.geli.keys"

A file for remembering the keys that are currently available.

geli_images="/var/geli/images"

The directory where images and device links are located.

geli_keys=".geli/keys"

The directory on managed file systems to poll for keys.
