Under this guix commit, wpa_supplicant service fails to initialize,
which takes out networking also.

bug#38653: Acknowledgement (wpa-supplicant dbus failure leads to networking service failure)

[Christopher Howard]

I took the neofetch pull after rebooting into an older profile, so some
data there might be suspect.

I suspect what happened is that you are using
wpa-supplicant-service-type, and also added 'wpa-supplicant' to the
(packages ...) field of your system configuration.  The latter will
include a D-Bus policy file for "fi.w1.wpa_supplicant1", which
wpa-supplicant-service-type also tries to register.

As a workaround, you can set (dbus? #f) in wpa-supplicant-configuration,
or remove 'wpa-supplicant' from the system packages.  If you want
wpa-supplicant installed globally, you can use 'wpa-supplicant-minimal'
instead.

Can you confirm?

Not sure how we can make this more robust.  The easiest fix is probably
to default to (dbus? #f); the only program I know that use the D-Bus
interface is NetworkManager, which has its own service in Guix.

I had more or less given up on bothering to try to upgrade system until
the next official guix release. That would be the ideal time for
another test run of this, so I could update both system and all my user
packages as well to the same target. Is there a rough idea of when the
next official release is coming?

Great, thanks for following up.  I'm closing this ticket now by adding a
'-close' to the bug email address.
