Tried openrc with Void, but I'm a big sysv fan ;D

Not much to add either.

Yeah for openrc I saw a good stackoverflow answer @ https://stackoverflow.com/a/78270127 that I'm thinking to apply everywhere, and steal OpenRC files from Alpine with some basic sed/awk to match paths with what debian/devuan expects. E.g., for PostgreSQL.

But yeah really want to know other folks experience with Docker and whether openrc is the best solution considering aforementioned requirements.

I haven't used Docker, so I have nothing to contribute there.

Welcome to Devuan Forum. :-)

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
