That's right. > When you run guix pull, a new guix is installed for the user who ran it. And who updates the system libraries and kernel? Root?

Upgrade or reconfigure? My operating-system declaration is the same. Not perfect, but I'll fix it later, with the help of 'reconfigure' (add noatime options as example). > I'm not sure what that is... can you give a more concrete example? I'll leave it for later, it seems particular. > I hope I could help a little :) In general, I understand everything. But! Update 0.15 -> 0.16 did not work. Errors are not saved, I will try again.
