Retaining the same icon label across different physical ports now works! :-)

Okay, don't show them in the GUI dialog. How about migrating the entire mediamanagerrc chunk for each device? Those four options would remain dormant under TDEHW, but would be there should TDEHW support them.

Observation (a different reason to copy the whole mediamanagerrc chunk for each device): TDEHW does not grep/inherit HAL settings in mediamanagerrc, requiring users to reconfigure each device that is different from the defaults. That is, each device under TDEHW defaults to the defaults. Users have to uncheck the "Use defaults" check box and reconfigure the device. Not to mention having to reconfigure the icon label. Paper cut nuisance, especially when we want TDEHW to be as seamless as possible --- the basic idea of "never breaking external interfaces." As both schemes use UUID I'm hoping this chunk copying should be straightforward. :-)

Aargh. :-) Rebuild again!

Okay. You have that particular set of FIXME messages in your queue. :-)

More information:

CD/DVDs: Not sure how this works, but the following happens when I insert a disk under both HAL and TDEHW:

* An icon appears on the desktop. The icon label is the name of the disk label, such as "Slackware64-current DVD."
* A dialog appears asking me what to do.

Then this happens under HAL:

* The disk mounts to a mount point the same as the disk label, such as "/media/Slackware64-current DVD" (Pretty!)

Under TDEHW:

* The disk mounts to the mount point of "/media/sr0" (Functional but not pretty)

Is there a way to get TDEHW to use a mount point like under HAL? I do not have anything in mediamanagerrc for optical disks. I don't know how TDE/HAL creates/uses a mount point that matches the disk label. I'm guessing something in the halbackend code that can be copied/pasted into the tdehwbackend code? :-)

* Compact flash disk icon: USB device rather than sd_mmc device: I'll test with the latest patches.
