I have resolved this problem, as follows.  Apparently, under SunOS 4.0.1,
Roadrunners are shipped with a 4096 kbyte limit on datasize hard-wired
into /bin/csh.  The statement "unlimit datasize" in .cshrc fixes things.
This limit did not exist in the version of /bin/csh shipped with 4.0, as I
verified by restoring it and checking.  Nor could I find any notice of it
in the Sun literature.  Then again, I had a beta version of 4.0, so I
don't know for sure what was shipped with the final release.

Alan Evans (evans@cunixc.cc.columbia.edu) replied:

  Your boot problem was the following:

  Your machine as a standalone wants to be a YP server and client and
  when it tries to start ypserv in rc.local, it can't because the YP
  database is in /var/yp which, since /export/var/localhost is mounted on
  /var, which doesn't exist until the /dev/sd2h partition is restored. For
  that matter, /tmp is in /dev/sd2h as well in your configuration. Nothing
  in the clusters is actually needed to boot, even on a networked machine.

(Incidentally, this verifies that the instructions are, in fact, wrong,
since the machine they refer to is configured the same way.  My initial
analysis of the problem -- the idea that something in .../clusters was
needed -- was also wrong!)
