OK found out how to do it. I wish someone would write this down. Its so
frustrating trying to work out how stuff works.
For the record :-
Hal uses the config files in /usr/share/hal
(Why they are not in /etc like all the other config files I do not know)
The files are in XML format and are processed by fstab-sync See 'man
fstab-sync' for clues.
The default settings are controlled by /usr/share/hal/fdi/90defaultpolicy all
the files in there are processed when a device is found. If the device
matches a config then it is applied.
User specific config is found in /usr/share/hal/fdi/95userpolicy these files
are processed after the defaults. Do not edit the default files. They will be
overwritten when you upgrade your linux. Make all edits
in /usr/share/hal/fdi/95userpolicy. See /usr/share/doc/hal-0.4.7 for examples
To get my mp3 player working correctly I created a
file /usr/share/hal/fdi/95userpolicy/storage-policy.fdi containing
<?xml version="1.0" encoding="ISO-8859-1"?> <!-- -*- SGML -*- -->
<deviceinfo version="0.2">
<!-- Example: Match a volume from an USB Storage Based mp3 player
by the file system UUID assign a mount point and set the sync
option in fstab.
NB: When reformatting the volume a new UUID will be
used and this rule will have to be altered -->
<device>
<match key="block.is_volume" bool="true">
<match key="volume.fsusage" string="filesystem">
<match key="volume.uuid" string="0C15-8CCD">
<merge key="volume.policy.desired_mount_point"
type="string">mp3player</merge>
<merge key="volume.policy.mount_option.sync" type="bool">true</merge>
</match>
</match>
</match>
</device>
</deviceinfo>
where the uuid string for the player is discovered by running
hal-device-manager and looking at the advanced tab when the device is plugged
in.
Yes Anne I will put it in the Twiki
