After a bit of circus, I have my simh 8650 back up and running. One new 
thing to make people aware of:
/boot is broken in recent build from current. Don't know exactly what 
the problem is with that. boot halts rather quickly, with no output. 
Moving in an older version works. But people need to be careful, and 
have some backup plan (disk/network) around in order to be able to 
recover in case /boot gets broken.
Also, a build from about two weeks ago broke everything when I installed 
userland. I suspect some shared library was the problem, but could not 
really investigate that well. A build from yesterday worked better, but 
it was a bit of an exercise to get the new set onto the existing disk 
and unpacked, in order to recover. Again - at the moment I would really 
recommend that people make sure they have some alternative disk with a 
system on it, or a netbootable system around that is know to be good, so 
that you can recover if things go bad with the installation of the 
latest build...
