I'm afraid that you're still missing the point. I'm not talking about
media. The DRIVE is not present at boot time. No /dev/acd0 to point the
symlink to. I insert the drive and use atacontrol(8) to connect and
/dev/acd0 appear, but no /dev/cdrom. In some platforms ATA disk drives
are just as removable as USB devices.
That's why I thought that devd might be the right approach.
