initial configuration is ignored, as it will be substituted with the
coordinates received from i-PI before forces are ever evaluated.
A note of caution when using potentials that contain long-range
electrostatics, or that contain parameters that depend on box size:
all of these options will be initialized based on the cell size in the
LAMMPS-side initial configuration and kept constant during the run.
This is required to e.g. obtain reproducible and conserved forces.
If the cell varies too wildly, it may be advisable to reinitialize
these interactions at each call. This behavior can be requested by
setting the {reset} switch.
