Understood, I am sure we will discuss more on this in a different thread :)

The only reason I never used the raw API because I do not want to
reimplement the swap logic in my code. It is easier to use the system
commands directly and I have other projects which showed this can be
easier to maintain.

Note: The biggest reason to avoid system commands through shell is
performance, which is not a problem in our case.

I agree, /etc/cloudtoserver.conf is this filename sounds good?

Okay, I will ping you to know more on this.
