>Environment:


System: NetBSD speedy.whooppee.com 8.99.7 NetBSD 8.99.7 (SPEEDY 2017-11-29 22:03:05 UTC) #0: Wed Nov 29 23:14:50 UTC 2017 paul@speedy.whooppee.com:/build/netbsd-local/obj/amd64/sys/arch/amd64/compile/SPEEDY amd64
Architecture: x86_64
Machine: amd64
>Description:
For a pseudo-device which can have children attached, the ioconf.[ch] file
generated by config(1) (and the Makefile IOCONF= directive) is wrong.

It generates a single list-ending {NULL, NULL} entry, rather than providing
an initial entry with the pseudo-device as its name and attachment name.

>How-To-Repeat:
Create a ioconf config file pad.ioconf containing

	pseudo-device pad

Then, config -s $SRC -b $OBJ pad.ioconf

Observe at the bottom the cfattach data.
