Boxes that physically live in my home are mostly Manjaro. They’re also not externally accessible from the internet.

Anything in the cloud I standardize on Debian. Two distros and consistency makes maintenance much easier.

Anything in a container runs whatever it was built on because porting a docker compose file from, say, Alpine to anything else is just not worth the time and energy.

From where I sit, not a lot of reason to do it. It’s a bigger pain to deal with your own CA than to just use LE.
