Yeah, the YAMLification of everything kinda killed my ability to understand "everything". Previously, if you knew the Linux userland well, I felt like you could figure anything out with enough digging.

Take CI for example, it was Jenkins and it ran a csh/bash/zsh whatever script and captured the output. Nice and simple (even if the scripts sometimes got insane).

GitHub actions is nothing like that. Weird home grown extensions to YAML with their own idiosyncrasies and dynamically pulling in plugins from god knows where. You can't just take a workflow and execute it locally like you could with a bash script.

And worse: GitHub Actions not a full-fledged programming environment by itself either, so you're inevitably going to have to deal with nontrivial shell scripts on top of all the YAML mess.
