Thanks for that.

I will look in to that, I am curious about that too.

I did use complete 2.1 userland that I downloaded from netbsd torrent. I 
downloaded iso image and used that to install 2.1
The config crashes like this - when I try to run it with or without 
parameters it dumps core with following message:
Bus error (core dumped)

I don't know how netbsd maps mips exceptions but if this is a bus error 
exception, config is accessing non existent memory or hardware. Although 
I would expect TLB exception first because I would imagine that netbsd 
is using memory protection.

It does mention about daily snapshots. Thanks. So that means I would be 
better off getting my sets from these directories rather than from the 
torrent. I will upgrade and see how it goes.

Thank you for the info.
