Just spit balling ideas here, how much of the problems containerizing is meant to solve would be solved by merely static linking? Because it feels like that's what containers are mostly used for. Static linking + a sandbox to get most of everything. Using shared libraries but then shipping the .so's in a container defeats the point of a .so in the first place. If the reason containers are okay now since disk space is cheap, why not return to static linking of executables?
