: Small amplification on this - the acd* devices don't work (can't :mount them or use burncd get device not configured errors) but the :corresponding cd* devices via atapicam work perfectly both for mounting and :burning DVDs with cdrecord (presumably burning CDs will work too I haven't :tried).
If you do a full system upgrade the new MAKEDEV will create the proper acd* devices. In particular, acd0 in HEAD was still running through the disk layer which was checking the media size and preventing burncd from being able to write. The new acd0 uses the proper minor number to bypass the managed disk layer entirely. acd0a mountable compatibility partition acd0c mountable compatibility partition acd0 raw device access (burncd will work with this) acds0 compatibility slice, generally not used unless you want to read the fake disklabel.
