yes installation + start

you are right, my list was not correct, I reused the one from the
healthcheck tests we made some changes due to the depenencies
when we installed incrementally, we installed AAF and the common
databases in core (even AAF healthcheck is in small)

please note that we now install everything in // and do not do it
incrementally.

yes you are right, the common maria DB as well

agree
that is why we are now installating everything at once relying on helm
chart dependencies.
