Agreed on principle.

However, I'd like we use the same constructs in all our dockerfiles, for
consistency sake.

And even if I did not expend too much time at making the Alpine image
reproducible, I expect that we can ultimately make it so, if it is not
already.

In fact, I even expected people to show up and say "hey! what you did
makes ofr a reproducible image," or "hey! here's how you can make it
reproducible." ;-)
