- Possible to change the default in the base system in a stable
way.
The change from NO_HESIOD TO YES_HESIOD wasn't a big deal to most of
our users, but the desire to have someone say "I want to build HESIOD,
reguardless of the default" wasn't possible in the old system.
The other item that's desirable is to have per-tree defaults for these
w/o needing to redefine the system make file. That isn't dependent on
these changes, but is a highly desirable thing. I've some patches
that implement that in a brute-force kind of way.
