zypper didn't cross compile easily and had a fairly nasty dependency
chain if I remember rightly including things like boost. We had quite
an extensive patchset against it and libzypp which could never be
upstreamed:

zypper was also hostile to rpm5 if I remember rightly.

Switching to something python based was much lower overhead on the
system compared to C++ and boost.

Cheers,
