I see. So if I've got a synced jail and host then top will work? I
thought top never worked inside jail for some memoryissue or something
like that?

I think I should go and rebuild my jails too. It's just a bit of work
with three jails, thank god that I've got a fast box :)

Still the issue with config-files but I think I'll back them up and
just restore them.
