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
