Well, doesn't that depend on your package manager? With pacman I can add a custom hook after install to update all flatpaks. I'm sure it could also be done for all snaps and AppImages if I would use any of those.
Isn't there a similar hooking mechanism in apt or yum?
Don't forget about timecop
I would have expected to see this story way higher in this thread!
We cannot forget about the wiki, which is a great resource for not only the Arch distro, but for any Linux install.
Seriously, the ease of installing any and all programs from the main repo's or the AUR is such an extreme advantage over all other distros!
And it makes keeping your system and programs updated a breeze.
