Improve system integration for Host

This is a spanning issue as we have multiple issuer related to host integration with either windows service or systemd flows. We should reconsider the integration as such rather then try to solve each of these issues separately.

Start by identifying the related host-integration issues for Windows service and systemd flows and compare the problems they describe. No files, tests, or entry points are named, so first establish the unified scope and affected integration areas. Done means agreeing on a cross-platform integration direction rather than handling each issue separately.
