Endless ways, which is why I do not understand why sudo is ever used anymore, especially in production.
replyYou do not need root to do anything in Linux these days anyway between Namespaces and Capabilities so there is really no reason for root to be accessible at all or have any processes running as root post boot.
I dont mean to be snarky, can you run `pacman -Syu` without root with "new" tech? Or do you mean in general on production systems or whatever?
replyPlenty of package managers can install to an arbitrary directory like ~/.local. Each user, or even each project, can have its own rootfs full of software.
replyThe only things I tend to have running at the system level are a kernel and init and maybe openssh.
