I've made [candalf](https://github.com/jarmo/candalf) to setup my own PC and servers by using simple shell scripts instead of using something more complex like Ansible or similar. It's been used by me to manage production servers (physical and VM-s) running Linux/FreeBSD for years now and I'm also using it to configure my own laptop (Linux) so that if I install OS from scratch I can get up to speed really quickly and to also have everything "documented" in the scripts to not waste extra time in the future.

I recently improved it a little to also support macOS, but have not used it for production usage having that OS.

Maybe someone else also finds it useful. If not then also no harm is done.
