I think solved it, this is how my file system is layed out:

a 750M /
b 512M swap
e 3500M /usr
f  500M   /tmp
g  500M   /var
h  4.5G     /home

For some strange reason it seems like NetBSD 1.6.1 wants the e partition 
to be reserved for /usr and nothing else. 

This how my file system was layed out with the segmentation fault -core 
dumped:

a 750M /
b 512M swap
e 500M  /tmp
f  500M  /var
g  3500M /usr
h 4.5G    /home

Now it's time to for me to try and fix host name lookup failure.

Thank You
