Using volume mounts vs bind mounts for the IoT Edge system modules

[anttikes]

The documentation instructs using bind mounts for persistently storing the data of edgeAgent or edgeHub modules on the host filesystem.

Docker's own documentation recommends using volume mounts instead.

Is there any clear reason why bind mounts are preferred in the documentation? Would the same benefits (i.e. robustness) be achieved by using volume mounts?

In what kind of a situation would it be necessary to manually manipulate the files persisted by the system modules from the host side?
