 I am not sure how you would do that. I am following these instructions:
 http://9track.net/pdp11/rsx4_sysgen.

 The trouble is that after restoring the RSX-11M+ 4.2 tape, when I reboot
 from the disk it gives repeated disk allocation errors, presumably through
 lack of space. Is there a step that needs to be added when first restoring
 the tape to the hard disk? 
Not sure what errors you are seeing, but it sounds weird.
Anyway, the normal way to run M+ from an RL02 was/is to use the 
pregenned system for an RL02, which has all the necessary bits stuffed 
in, and everything set up. Ready to go.

Generating your own system for running on an RL02 takes some careful 
consideration...
