I have never automounted my cd-rom drive, so I don't know if acd0a=acd0c for this purpose, but ISTR trying acd0a unsuccessfully for playing music CDs, while acd0c worked. Using Google Groups I see posts referring to SCSI cd-rom drives using /dev/cd0a and /dev/cd0c, so perhaps that's the significance of the missing "a" at the front.
