i want to run update once not 9 times every time I have to update.

im this close to giving up and just using git and github for this

edit with additional context: for installed applications.

Right now I've got things from cargo and npm and pip and apt and go-get and snap and tasksel and homebrew

edit: @wiggles in the comments recommended Topograde which sounds like it solves this, and also it maintains it so go check it out maybe
