Wow, this is really cool - and long overdue.

I've been thinking for a while that some bor^H^H^Henterprising soul
should hack install(1) so that if a specific environment variable is
set, it writes the file to a tarball instead of writing it to disk.
Unfortunately, there would still be a ton of ${LN} etc. that would need
to be handled somehow.  Perhaps install(1) should have an option to
create symlinks so we could use that instead of ln -s, in the interest
of reducing the number of different tools used during installation.

(BTW, I find INSTALL_OWN confusing - how about UNPRIVILEGED_INSTALL or
USER_INSTALL?)
