I am aware that Arch and derived distros recommend always keeping the system up to date, however I have chosen not to do this. I update occasionally, mostly if there is actually a problem I need to fix, and usually I update only the relevant packages, not all. That said, there are a handful of packages that I do want to stay up to date with.
I am using Manjaro, with Cinnamon as my DE. I constantly get the update notification about hundreds of updates, most of which I don't care about.
pacman -Syu also results in a long list littered with irrelevant updates. I'd like to have a whitelist system: The update notifier should only tell me about updates to packages I've specifically marked as interesting. I should also be able to run a pacman command that will only update the packages on my whitelist, and their dependencies (but not notify me about dependency updates).
How can I do this?
