Fixing burncd should be a priority, this PR gets it into the "must fix 
queue" before the next round of beta or RC releases. Yes you have 
identified what is causing it to not work, but you have not followed 
through. The next step is to assign it to someone to work on it now. 
Thats the whole idea of the PR system and beta testing.

If burncd is not going to work in 9.0 then it should be removed from the 
release all together. Has any research been done to identify other 
system commands or ports that changing the system default from acd0 to 
cd0 effects?
