+.TH AUTOFS.UDISKS 5 "22 Aug 2012"
+.SH NAME
+autofs.udisks \- autofs configuration for local removable devices
+.SH "DESCRIPTION"
+The automount udisks module is able to manage removable devices on the
+local system by connecting to the message bus daemon
+.BR dbus\-daemon (1)
+to monitor all device events of the
+.BR udisks\-daemon (8).
+To grant access for local users the automount
+udisks module also monitors users sessions hold by the ConsoleKit
+daemon, compare with description of the PAM module
+.BR pam_ck_connector (8).
+.P
+To use the automount udisks module an entry in the Master Map
+.BR auto.master (5)
+has to added, like this:
+.sp
+.RS +.2i
+.ta 1.0i
+.nf
+.I /media/autofs udisks:@@autofsmapdir@@/autofs.udisks \-\-timeout=5 \-\-ghost
+.fi
+.RE
+.sp
+Please be aware that format of the file
+.R autofs.udisks
+does
+.B not
+follow the common format of the automounter maps but is an XML
+configuration file. This file is used by the automount udisks module
+to generate the automounter map on the fly.
+.P
+An example of this file is:
+.sp
+.RS +.2i
+.ta 1.0i
+.nf
+<?xml version=\[dq]1.0\[dq] ?>
+<AutofsUdisks enable=\[dq]true\[dq]>
+ <MountOptions>
+ <Common>uid=$UID,gid=$GID,nosuid,nodev</Common>
+ <DiskById value=\[dq]usb\-USB_Flash_Disk_XXXXXXXXXXXX\-0:0\-part1\[dq]>
+ uid=1002,gid=501,user,nosuid,nodev,exec
+ </DiskById>
+ <DiskByLabel value=\[dq]MyPersonal\-DVD\-x86_64XXXX\[dq]>
+ unhide
+ </DiskByLabel>
+ <FSType value=\[dq]vfat\[dq]>fmask=0132,dmask=0022,showexec</FSType>
+ <FSType value=\[dq]ntfs\[dq]>umask=0022</FSType>

+ <FSType>ro,nosuid,nodev,noexec</FSType>
+ </MountOptions>
+</AutofsUdisks>
+.fi
+.RE
+.sp
+The entries of such a XML configuration file are
+.TP
+.RB < AutofsUdisks >
+as the outer envelop. This level has exactly one attribute
+.BR enable =\[dq] true \[dq]|\[dq] false \[dq]
+which allows disabling the automount udisks module without
+removing the module its self.
+.TP
+.RB < MountOptions >
+is the only known entry below which is used to list the
+possible mount options, compare with
+.BR mount (8)
+as well as the variable substitutions mentioned in the manual
+page
+.BR autofs (5)
+for the format of the automounter maps.
+.P
+There are four possible entries below
+.RB < MountOptions >
+to help the the automount udisks module to generate the automounter
+map.
+.TP
+.RB < Common >
+is the entry which provides mount options applied to
+nearly all generated maps.
+This entry will be overwritten by the next entry.
+.TP
+.RB < DiskById\ value =\[dq] \fIID\fR \[dq]>
+is the entry which provides mount options which are applied
+instead of the
+.RB < Common >
+entry if a device is found with an
+.I ID
+listed below
+.IR /dev/disk/by\-id/ .
+This entry will be overwritten by the next entry.
+.TP
+.RB < DiskByLabel\ value =\[dq] \fILABEL\fR \[dq]>
+is the entry which provides mount options which are applied
+instead of the
+.RB < Common >
+or
+.RB < DiskByLabel >
+entries if a device is found labeled with
+.IR LABEL .
+Such labels can be detected by the super user with the
+.BR blkid (8)
+command.
+.TP
+.RB < FSType\ [ value =\[dq] \fIFSTYPE\fR \[dq]]>
+those entries are used to apply file system \fIFSTYPE\fR specific mount
+options to a generated automounter map entry. There can be one
+.RB < FSType >
+entry without any file system value as a fallback for file systems
+not specified in the configuration file.
