Thanks for the answers John, Glen
I think John was right that it is better to build my own mfsroot and
then make config scripts etc.
The `sysctl -a` can do the thing with detecting the hardware etc. It
is a bit lammy but is working. Then dd fdisk bsdlabel and newfs do the
rest.
However if someone is there with an idea how to correctly build
sysinstall it would be wellcome.
greets..
Ivo
