I thought Ken said that, but anyway, it is true that CD-ROM and tape 
drives have their own `cd' and `st' device names, respectively.

This decision was made long, long ago; relative ordering is a two-edged
sword.  It is expected that anyone who uses NetBSD will compile their own
tailored kernel, which may include wiring down devices to specific device
names.  (Adding and removing kernel options is a much more common reason
you'd want to do this, anyway.)
