So perhaps this file should be treated as, um, whatever our equivalent
of a "conffile" is from dpkg-land.

That's unfortunate.  Perhaps either Python can be trained to write
updated copies somewhere else? Or maybe we can generate them
at package installation rather than shipping pregenerated versions?
(Would slow down builds of dependent packages, but those are the
breaks.)

Yes, on all machines; no; and ZFS.
