Single-user Nix installs are lighter weight, but also have a major compromise: the store is writable by the user. This means it is pretty easy for software you're using to accidentally change the store underneath Nix, and create unpredictable and unreproducible behavior. I think the multi-user install is a better Nix experience, even if the install process is spookier. Like is mentioned elsewhere, Docker does similar contortions to install itself. I wonder if it would have been more palatable if the Nix installer was less forward about what it is doing?
