Do you mean it literally invokes /sbin/modprobe?  If so, hooking this
at /sbin/modprobe and calling out to the container manager seems like
a decent solution.

Yes it does. Thanks for the idea, I'll see how this works out.

Would documentation guiding you in that way have helped? If so
I welcome a patch that does just that.

If someone wants to make this classy, we should probably have the
container counterpart of a standardized paravirt interface.  There
should be a way for a container to, in a runtime-agnostic way, issue
requests to its manager, and requesting a module by (name, Linux
kernel version for which that name makes sense) seems like an
excellent use of such an interface.
