[Mageia-dev] HAL woes

[Frank Griffin]

On a pre-/usr cauldron which has intentionally not been updated, wine 
apps have suddenly stopped being able to "see" mounted DVDs.

Checking syslog immediately after ejecting and reloading the disk, I find:

*******************************************************************************

Based on observation, the stuff timestamped 10:50:50 is the result of 
ejecting the disk, and the last few lines timestamped 10:50:54 are the 
result of reloading it, with the intervening 4 seconds consumed by 
reading the disk headers and such.

I seem to remember here that nothing is supposed to be using HAL, so 
it's puzzling as to why systemd would be trying to start it in response 
to the load.  It's equally puzzling as to why this should suddenly 
affect wine, when nothing's been upgraded (this worked 2 or 3 days ago).

The disk is correctly mounted and identified by KDE, and is usable by 
k3b and command-line utilities.  k3b also detects the load event, and 
switches its GUI prompt from "insert a disk" to the actual label.

Is wine still hal-dependent when it ought not to be ?
