The short story:

1) I cannot use sysconfig, I need to do it all manually. What has to be done? 
(Available tools: A text editor.)

2) I need to add a user manually to a system. All I have access to is a text 
editor. Not a fully working NetBSD system, just a linux nfs-server that hosts 
the root for a diskless NetBSD, and I need to add a user on that NetBSD 
system -- that NetBSD system is diskless, keyboardless and partially

Ok, so here's the current setup: I still can't get anything to work. Sortof. 

1) If I let it boot with rc.conf as: [comments striped for brievity]

if [ -r /etc/defaults/rc.conf ]; then
	. /etc/defaults/rc.conf




If I netboot that, nothing works: I can't login with SSH.

Now, if I append:

/usr/libexec/telnetd -debug 80

To the rc.conf file, I can actually connect to port 80.

But, obviously, it's refusing root access. How can I connect? Two solutions I 
can see: Allow telnet root logins (not a problem if it's only temporary) or 
create a user account... remember that I don't have access to the working 
system, I'll have to manually edit the config files. Any ideas on how to do 

What's the format for pwd.db?

They all look sane to me and to my interpretation of the manpages =P

Didn't =(
