Raw Revices in OpenSuse 12.1 and the udev-mechanism

Every time Suse comes with a new version of its operating system we must carefully have a look on how they handle raw devices resp. logical volumes. This week i  upgraded from Suse 11.4 to Suse 12.1, IDS remains unchanged on version 11.70. There is no substantial change in handling raw-devices by Suse 12.1, but it is very important to use the correct udev-file. otherwise you can get a surprise - may be that mouse and keyboard does not work....

Raw Devices on Suse Linux
