I am playing around with init systems to try and get a consistent experience whether inside or outside of Docker.

So outside of Docker default OS+distribution init system (e.g., systemd, openrc); but inside Docker I am figuring things out.
Lots of s6-overlay proponents… but what do you think of just openrc on debian derived distributions?

Explicitly: my use-case is creating deployment scripts where the same script can be used on any [Linux] distribution both inside or outside of Docker. I would also prefer not to maintain a large number of init scripts per deployment; but rather rely on some third-party to maintain this (e.g., Devuan, Debian, Alpine Linux, &etc.); preferably the same [first-party] maintainer as the base distribution.

Thanks for your insights
