Heh, for the record I am not working on this :-)

The spec [1] describes how inclusion of Ubuntu packages is supposed to
work. Roughly:

 - snaps can declare in the yaml which debs they need at runtime
   (include-debs:).

 - building the snap will fetch those (and their transitive
   dependencies), and put them into a debs/ dir. The yaml then
   declares "overlay: debs/"

 - our launcher will support a per-snap overlayfs on top of /, and
   mount debs/ (i. e. the overlay: value) on top of /

With that we don't need all the LD_LIBRARY_PATH stuff, and a lot more
debs will just work because they appear to be in the path they are
designed to work in.
