I agree with Bill, it would be easier to start from scratch. That said, the
patches from Crush and SLIND could be used as ideas.

One footprint-related issue with SLIND were big Perl dependencies. Perl is
necessary for postinstall scripts. We've used perl-minimal and stripped
unnecessary dependencies.

The list is valid if you want to make a generic distribution and do it right.
It is also the reason why Crush has been abandoned. That said, it's possible to
bootstrap a minimal system for a specific product in finite amount of time and
keep improving it. If we would manage to upstream the changes to Debian in form
of build options turned off by default and set up CI (ideally including the
cross-build stuff by Helmut & Co.), the effort might be somewhat more
manageable.
