How did you write it to the RL01 and what would it take to write it to rl02
assuming rt/kserve. Did you use guarenteed no bad block media?

a `Heriot-Watt stripped down 7th Edition',
If this is the version I have, which not only came from HWU, but is
running on one of their old machines, it's fairly standard. It was
build for a 'small machine', meaning one without separate I&D space,
such as an 11/34 (mine's on an 11/23 with 128KW and RL02s). There
are some extra drivers to support RX02s and stuff, but I think these
are just well-known additions from sources such as Boston. There's a
makefile to configure and build for a small machine.
It's missing some of the larger pieces of software, such as troff (nroff
is there, and the troff source AFAIR) and Fortran, and the tty driver is
modified (bigger!), but most other things seem to be 'normal'.
I have the source on 800bpi magtape (pity my drive is only 1600bpi) and
also most of it on RL02, though the RL02s are a bit disorganised.

Not true. They all did as bad blocks have been a fact
of life for all
computers since day one. Some of the ealy unixes used crude methods
from a perfomance standoint but, the bad block replacement was there.
Well, not day one, but that come pretty early. Quality of the magnetic
media wasn't really that good back then, so you usually *had* to
expect a few bad spots on any disk.
On PDP-11's, I would supect that Unix went with DEC's BAD144 standard
pretty fast. (When did that standard come, btw?)
Do read LIONS commentary. I was able to get a copy
from the local library
here in eastern MA (USA) along with several books on BSD design. Unix was
really ahead of the pack on many things.
Not to be a pain in the ass or so, but in what ways was Unix ahead of
anything?
Unix was just a small hack inspired by Multics, and looking at contemporary
operating systems, I'd say there were some that were way ahead of Unix (and
still are...)
Operating systems in the last twenty years have really retro-developed. :-)

Most RL02 are pretty good. Usually they don't have any bad spots in my
experience.
