It's exactly my task, to make every user able to run their own subhurd.

yes. but to be specific, it really depends on how we run boot.
If we run "boot -T device servers.boot hd1", what store_parsed_open does 
is to open the device by calling get_privileged_ports() and device_open().
In this case, there is nothing to do with /dev nodes, and my proc proxy 
might be able to give a help:-)
