Yes. The trouble is that only the system disk is mounted initially,
so anything needed to get the system going must be on the system disk
and NOT on any other public disk.

The best thing to do with public disks is "just say NO". Instead, use
a big enough system disk. That definitely was not a good RSTS
feature, though perhaps excuseable due to the small size of disk
drives in the early 1970s.
