This happened a few months ago when my NetBSD box failed because of
HDD breakage. I probably made something very bad while restoring my
system using NetBSD 2.0.2 installation CD (installed system is 4.0).

Thank you very much! Now I see what happened and where it is
documented :-) I restored my system being in single user mode like this.

 umount -f /dev
 cd /dev
 ./MAKEDEV all

It seems everything works fine now.
