I am beginning to appreciate a little more how containers fix this 
compatibility issue.
The only thing I need to figure out is how to get the most out of 
containers
optimisation-wise, i.e still getting a way to share common libraries 
between
same-generation apps. Otherwise, I see software distribution going full 
circle
