Given that we'd need to patch dpkg to look for the new
rules/control/whatever it wouldn't be hard for the patch to fall back to
/debian if /emdebian doesn't exist, or to add an option to 'behave like
normal dpkg', so I don't think this is serious problem. Package name
clashes/equivalencies is probably much harder in terms of being able to use
debian stuff on an emdebian system.
i.e. if we make all the emdebian packages have different names then you can
add debian packages in easily, but they'll bring in huge piles of stuff
because the depended-on-packages have different names too.
If the emdebian packages have the same names then you can't use stuff out of
debian without rebuilding, but library dependencies should work.
This is one of the the things that neds some more thinking-through to work
out best tradeoffs.
