This is not a high-priority item, but just a matter of curiosity...

I just finished un-upgrading our uVAX-I from VMS V4.4 to V4.3 (because
of the flaky DEQNA and our Internet software crapping out on it) and I
discovered some interesting things:

When I first installed V4.3 (after all reasonable backups and such)
and all chosen options from the SYSP, USER, UTIL, PROG, and other subsets,
the machine tried to boot up as a cluster.  (I had also installed DECnet
but not the End Node Key.)  [On bootup it complained that CLUSTRLOA.EXE
was missing.]  Using B/5, I found that AUTOGEN had set my VAXCLUSTER to
a value of 1, which I reset to 0 and made DRYCAS happy to be alone.

After this was done, I noticed that the PID for SWAPPER was 00000010.
Normally (when I ran 4.3 before and when I was running 4.4) it was
00000040.  After I installed a few more packages, SWAPPER returned
to its normal 00000040.

On our 8650 running V4.4 (and recently clustered), the PIDs are
2140xxxx (now, anyway...sometime before I could have sworn they
were 2040xxxx).

Am I confused or is there logic to this?
