What parts of a system configuration (in the most broad sense of the word), or what changes thereof should be
(or are) used for the particular execution? Most of the time, we are concerned with simulated executions, but
in the future it is possible to tweak configuration in a way that will be safe to run in production.
(For example, just ignoring some parts of it, e.g. some resources.)
For the time being, only rudimentary options are here.
