I think this clause should be used to enforce this extremely important
restriction. IMHO if a package cannot guarentee availablity it should not
be marked essential and it should be *clear* that it *cannot* be a crucial
part of the system until that is fixed.

Almost all of the essential packages presently have the property that if
they ever stop working the best case is that you cannot install more
packages without a rescue step, and the worst case is that your whole
system is foobar.

Basicaly, I would see it more as a contingent for becoming essential - if
we accept that right now nearly all the essential packages have this
properpty then a) new essential packages we decide to add must also have
this property and b) any upgrade to any existing package must preserve the

Personally I would increase the strength of the wording to be more like:
  An essential package is one that can never stop working. This means any
  dpkg abort must leave the package properly functional.

IMHO just being able to live in the unpacked state is not good enough.
