Our guide on mounting disk resources / changing agent resources is providing information exclusively for additive mutations - which is correct.
However, our users may believe that the same works for removing resources. Which is not the case. We need to be very explicit on that to prevent users from running into a trap.
A simple resolution would be adding a paragraph or two on that.
A more complex resolution would be explain bit-by-bit on how to e.g. remove dynamic reservations or persistent volumes from an agent.
