What you want is to make HAL mount your device for you. I'm not an expert
for HAL but I use it for some purposes. Consider this mail as a
suggestion and improve it. :) You should have at least basic knowlege of
XML and shell scripts.
Place the following file into /usr/share/hal/fdi/policy/20thirdparty.
Replace volume-id-here with the volume uuid of your partition. You can
get it for partition sdd3 as follows
hal-get-property --key volume.uuid --udi $(hal-find-by-property --key
block.device --string /dev/sdd3)
--- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8<
---
<?xml version="1.0" encoding="UTF-8"?> <!-- -*- SGML -*-
-->
<deviceinfo version="0.2">
<device>
<match key="volume.uuid" string="volume-id-here">
<append key="info.callouts.add"
type="strlist">mountscript</append>
</match>
</device>
</deviceinfo>
--- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8<

In /usr/lib/hal/scripts you have to place the script "mountscript" used
above.
--- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8<

#!/bin/sh
gnome-mount -h $HAL_PROP_INFO_UDI

This SHOULD mount your partition as soon as hal sees it. Maybe it is
possible to call HALs mount-method from the XML script directly. This
would make the shell script obsolete.
I've been looking into XML, etc. and thought that I knew enough to be
able to understand what's going on. Apparently not. The drive is not
being mounted. Most likely the script isn't being called at all.
Some questions:
What does the environment variable $HAL_PROP_INFO_UDI do? It looks like
it has the value of the hal property "volume.uuid"; is this true? What
other environment variables are set when the script is called?
Is there any convenient way to get hal to log its activity at boot time,
similar to invoking it (as described in the man page) as
# /usr/sbin/hald --daemon=no --verbose=yes ?
Why isn't my setup working? The needed info is (hopefully) below:
The XML control file:
$ cat 95-mount-usb-drive.fdi
<?xml version="1.0" encoding="UTF-8"?>
<deviceinfo version="0.2">
<device>
<!-- Mount (usb) drive with label usb-disk -->
<match
key="volume.uuid"="9dd976ce-a988-42a2-857d-06c3079675e7">
<append key="info.callouts.add"
type="strlist">hal-mountscript-jon</append>
</match>
</device>
</deviceinfo>
The mount script:
$ cat /usr/lib64/hal/scripts/hal-mountscript-jon
#!/bin/sh
gnome-mount -h $HAL_PROP_INFO_UDI
