[gentoo-user] mediamanager tries to open wrong path

[Gerhard Hoogterp]

Hi,

I try to install udev/hal/pmount  in such a way that my usb devices are 
automounted. But not with a changable name in the media folder, but with a 
fixed name like /mnt/camera (or /media/camera.. whatever. As long as it's the 
same every time..)

At this moment most things work, but when I add the mountpoints to fstab 
things go wrong. kde pops up a window and an error "permission denied". The 
later is understandable as it seems to try to open a mount in the media dir 
which doesn't exists instead of the mount point as given in the fstab. 
Regretfully the /mnt/camera isn't mounted either. 

So adding a line to the fstab file just screws up the system as  it seems. 
Removing it leaves me with changable names in the media folder (/media/disk, 
media/disk-1, depending on what's happening..

So I see two sollutions: 

- Or the mediamanager whould open the path as givien in the fstab (but where 
do I tell it to do so?)

- Or I should be able to give the pmount a label (the second parameter) so it 
creates a /media/<label>. But again.. where can I do this. 

The main reason that I want a fixed name is for programs like digikam which 
expects such a path for importing images.  Besides, on of the howtos 
suggested that using the fstab should work. So why doesn't it..

Anybody a suggestion?

Adding a line in fstab overrides the naming that pmount would otherwise
use, but you have to add "users" to the options to allow it to be mounted
as a normal user. Generally, fstab and HAL-driven automounting don't play
well together.

You need to set up udev rules to have persistent naming for your devices,
then KDE will use this to name the mount point. See

Apparently.. the "users" flag was already added (noauto, user) so that's not 
the problem.. 

/dev/minolta  /mnt/camera  vfat  noauto,user 0 0

to be precise.

Done too. udev creates a nice /dev/minolta which I would like automounted 
to /mnt/camera (or even /media/camera)

If only pmount.allow would allow for a <device> <label to use>. But as it 
seems that would make life to simple eg. less interesting..;)

Thanks,
 Gerhard

pmount.allow only specifies which devices may be automounted. When
mounting, pmount gets the name from either the disk's volume name or the
device. Does your camera use a removable memory card? If so, try putting
it in a card reader and setting the volume name with mkdosfs or mtools.
My camera formats the card with a volume name of CANON_EOS, so it is
mounted at /media/CANON_EOS.

Well it does, but it does feel a bit of an ugly hack to have to label all my 
cards "camera" just to get hal/kded to behave. Besides, the card isn't the 
camera.. so even on a logical level it's wacky.. 

Anyhow, guess it's the best for now. 

Thanks!
 Gerhard

There is a way round this. It is possible, somewhere in the config of
pmount/hal, to have devices mounted according to the /dev name only. I
can't remember where this is, but Google and/or grep should find it.

Personally, I prefer to use the volume name, because I may be using the
card in the camera or a card reader, and the dev name varies according to
which I use, whereas the volume name stays the same. It makes dealing
with multiple mounted cards much easier.

If your camera mounts as USB-storage, the camera is simply acting as an
expensive card reader.

After some searching around I found the HAL 0.4.0 specs 
(http://people.redhat.com/davidz/hal-spec/hal-spec.html) offering all the 
info needed to write my own policy:

<?xml version="1.0" encoding="ISO-8859-1"?> <!-- -*- SGML -*- -->

<deviceinfo version="0.2">
  <device>
    <match key="block.is_volume" bool="true">
      <match key="volume.fsusage" string="filesystem">
        <match key="info.parent"
		 string="/org/freedesktop/Hal/devices/storage_serial_KM_DYNAX_7D">
          <merge key="volume.policy.desired_mount_point"
		 type="string">camera</merge>
        </match>
      </match>
    </match>
  </device>
</deviceinfo>

The line that makes it work for me is the <match key="info.parent" .. > which 
is true when my camera (a dynax 7D) tries to create an mount point. The 
result is a /media/camera which I can use in digikam to import photo's..

True, but the card is also not the cardreader..;-) Anyhow, for me this works 
as it looks at the camera and not at the card.. 

Thanks for thinking along!

True, but as I mentioned elsewhere, I prefer that. The source for Digikam
is the same whether I leave the card in the camera or use a reader.But
it's good to know for sure that you can do it the way you like too.

I don't think it would matter in this case but for future reference,
there is a difference between user and users.  I learned that the hard
way once.
