not fully idempotent yet, they make small changes:

• docker (hmm need to see what is going on, takes a bit of time. Should be idempotent because it's only dnf module. Ensure old deleted - says changed even though they dont exist)

TODO:

add bash completions or man pages for custom binary installs...
