Doesn't quite work for me with a fresh NetBSD/i386 5.0_RC2 installation

I presume you get this message throughout on every operation?

This was a completely clean disk, so there was no existing GPT table. 
Hence I started at this point:

I presume you got a message suggesting you ran:
dkctl rsd0d addwedge dk<N> 34 11714691005 <type>
(why doesn't it pass through the type from the -t option?)

The command didn't work for me (no such file or directory) until I put 
/dev/ in front of the device or used the plain device name like below:

> # dkctl sd0 addwedge dk0 34 11714691005 ufs

i.e. the informational message is misleading

Yes, that all looks the same.

newfs: /dev/rdk0 partition type is not '4.2BSD'.

What was needed was a reboot before doing the newfs.
