The SMART agent plugin now attempts to exclude devices which can read CDs. Such devices do not support SMART and not excluding them can lead to hanging smartctls processes. The plugin attempts to exclude such devices based on the output of udevadm, if this command is found.

Note that you need to update the agents on affected linux hosts for this werk to come into effect.
