I'm sure many people would find such a tool useful.

Speaking *personally*, I have been moving away from doing package
management inside containers.  I have a not-yet-published tool
which builds containers in a more sophisticated way 
using *host* side package management.

That tool isn't ready yet (it depends on hawkey/librepo), but I did recently put together
a trivial wrapper for yum that does a subset of it (with some
minimization support):


(No new code or anything interesting there, it's just capturing
 and slightly polishing a variant of the many, many similar
 invocations one can find around)

In this model, we're not using Docker layering for code - the container
will contain exactly what the RPM dependencies of the input.  A great
thing about Docker though is you can still use FROM on images
generated this way, and add in custom configuration, etc.
