I want to install Debian Linux (on a 2009 Macbook Pro), opting for the OpenRC init system. By default, Debian uses Systemd. During the installation, I did not see any option to choose the init system; how can I choose OpenRC (or Sysvinit)?
Once Systemd is installed, can I replace it with OpenRC, or is it not feasible due to how invasive Systemd is?
How can I opt for OpenRC during installation?
Is it possible to have more than one init system, and choose which one to use through, e.g., a configuration file?
