Generally speaking, you have to remember that there are at least three
profiles involved in Guix:

your user's profile (managed with 'guix package' as a user),
root's profile (managed with 'guix package' as root),
and the system profile when you use GuixSD (managed with 'guix system'
as root).

the operating-system declaration in your config.scm file is used to
instantiate a new system profile, which is separate from root's
profile. So you use that file with 'guix system reconfigure'. 'guix
package -u' will only upgrade root's or your user's profile.

The kernel is installed in the system profile, not in root's profile.
System libraries do not really exist in guix, because of the
functionnal model. So upgrading the system profile will upgrade system
software, grub and kernel as well as system services, but it doesn't
update anything in root or users' profiles.

A full upgrade consists in running 'guix pull' once as each user
(including root), then running 'guix package -u' (or 'guix package -m'
if you use a manifest) as every user, including root, and 'guix system
reconfigure' to also upgrade the system profile.
