Can't the daemon live outside the container and shuffle stuff in?
IOW, there seems to be little point in containerizing things if you're

FWIW, I think that the capability evolution rules are crap, but
changing them is a can of worms, and enough people seem to thing the
status quo is acceptable that this is unlikely to ever get fixed.
