I quite like the grml-zsh-config git prompt. Its fast and simple.

There is also a authy-export tool that makes it pretty easy to export all the tokens to selfhosted pass repo.

fedora will be fine as it is the upstream provider of rpm build files

fedora -> centos stream -> RHEL

Rocky Linux and Oracle Linux that take the RHEL sources without contributing back are having their src rpm access cut.

systemd is one of the best things that has happened with linux. Instead of random shell scripts that work differently on each distro, now you have a single ini conf file for your service that configures automatic restarts, sandboxing and activation in a easy to use way.

Maybe a bit different but I quite like WikiJS https://js.wiki/

I have it setup to use PostgreSQL and its built in text search engine and every page is also saved into a git repository.

I have quite a lot of notes written there over the years and im pretty happy with it.

LFS is fun. Its like cosplaying as a package manager :D

same, its pretty solid for a meme os. For anything else I usually use Debian.
