  | 	or, least surprise.

It doesn't actually affect either (the only difference is for
people who do kernel upgrade alone, and they ought get the new
stuff, not skip it).

Whichever way it is done, the default changes.  sysctl.conf can
be altered to change the default to whatever is desired.  So, assuming
the change gets made (and no problem with that), either way it is
done has the same effect.

However, in general it is better for the various .conf files to get
used to alter the system defaults to some local preferred value.  That
way it is easy to see what is a local change, and what is normal.

The way you initially suggested, by removing sysctl.conf people would
end up with a system that is different from the NetBSD default in a
non-obvious way.

I agree with others, just change the kernel defaults (and if you really
think that anyone might need to revert them, put commented out entries
in sysctl.conf showing how that would be done, with comments indicating
why it might need to be done).
