       IvmConfigConditions.xml  -  rules for processing hardware conditions by


       IvmConfigConditions.xml specifies hardware conditions to be  caught  by
       ivman(8),  and  allows  running  of  certain commands when devices emit

       IvmConfigConditions.xml is parsed as an XML file.  The general form  of
       the file is:

        <?xml version="1.0" encoding="UTF-8"?>
        <ivm:ConditionsConfig                                    version="0.1"

           <ivm:Match name="matchname" value="matchvalue">
              <ivm:Condition name="conditionname1" exec="command1" />
              <ivm:Condition name="conditionname1" exec="command1" />



       Each time a condition is emitted by a device, this file will be parsed.
       If  the Match rule matches the device on which the condition came from,
       and the  Condition  rule  matches  the  name  of  the  condition  which
       occurred,  then  the  command  specified  in  the ’exec’ option will be

       A Match element can have any of the following names:

                   Whether or not HAL specifies that a device can  and  should
                   be mounted.  Must be "true" or "false".

                   The string in place of "anything" will be taken as the name
                   of a HAL property string for the device, and the  value  of
                   the  property  will  be  compared  to the value given.  Run
                   ’lshal’ to see a list of HAL properties which can  be  used

            *      Match every device.  Use with care!

       As many Matches can be nested as is desired.

       Condition   names   usually   take   the   form   of   something   like
       ’ButtonPressed’, which may occur when an ACPI-enabled button is pressed
       on your machine.  See the HAL specification for a full list of possible

       The exec attributes of  Condition  tags  support  substitution  of  HAL
       device  properties.   This  is accomplished by surrounding the property
       name with $ symbols.   For  instance,  if  $hal.volume.mount_point$  is
       within  a  command,  it  will be replaced with the volume’s mount point
       before execution.  No character escaping is done in  the  substitution,
       but the characters ’ and " are replaced with ?, so you can surround the
       substitution with quotes without fear.

       Remember that this is an XML file, which means  that  characters  which
       have  a  special  meaning  in  XML (entities) need to be escaped.  Some
       characters which are popular in shell scripting (&,  <,  >)  are  among
       these  special  characters.   As a quick reference, & becomes &amp; , <
       becomes &lt; , > becomes &gt; , ’ becomes &apos; and " becomes &quot; .
