Color me old-fashioned, but the new SL5 behavior of mounting a CDROM
in /media using the CD's volume name is annoying (and hard to write
scripts for). For example, if the CD is named "New Volume", it
mounts as "/media/New Volume" (a filename including a space). This
could be especially nasty if two CDROMs or two USB keys have the
same volume name.
Is there something I can tweak so that the CD on /dev/cdrom always
mounts as /media/cdrom or /mnt/cdrom ? I imagine this has to do
with autofs, but the documentation on that is sparse.
I think it is HAL/hald rather than autofs since we disable autofs and
still have removable media getting automatically mounted... :-)
If you have clashes then I *think* it will avoid using the same name but I
can't remember why I think this. Since SL5 the /etc/fstab file is no
longer updated for removable media devices so users can't directly use
mount/umount either but the gnome-mount utility (and possibly others!)
talks to hald to request mounts etc so it can be done from the
command-line.
I have a terrible little script I'm playing with atm which I've attached
to this message, it dumps some properties of any hal object which has the
volume capability (including device, volume.label and mount-path)... I'd
restrict it to just *removable* devices if I could work out how...
I have a feeling that just running 'hal-device' and parsing all the output
might be simpler than trying to get volume info the way that this script
does it. I was hoping that someone else had already written a nice piece
of perl to interact with hal but I've yet to find anything... Are there
any nice hal modules for python or some other scripting language?
