The man page for cdcontrol(1) is missing three environment variables. They are CDPLAY, CD_DRIVE and MUSIC_CD. The do the same as the documented DISC does. Fix: Apply this to /usr/src/usr.sbin/cdcontrol/cdcontrol.1: How-To-Repeat: Read the man page for cdcontrol(1) and compare it with the code.
State Changed From-To: open->closed Fixed in rev 1.16 and rev 1.8.2.5 of src/usr.sbin/cdcontrol/cdcontrol.1. Thanks!
