Is there any way to install NetBSD so as to be able to track -current while not
burning one's bridges of the stable distribution?  Could this be done within one
primary partition?  Maybe include relatively small f and g subpartitions for the
experimental root and /usr?  Packages like emacs, mozilla, perl, vim 6, pine and
others would be accessed in their normal installed places rather than being
installed in duplicate.  Is root invariably a?  Or could the disklabel be edited
to switch a & f, and e & g, and later switch back?

This question is also appropriate regarding a release version upgrade, if one is
afraid the new release might break something.
