Hello, Ricardo Wurmus!

I have rewrote my config, including all modifications into the one (modify-services) function, I've added dhcp-client-service-type to (services) section.

But networking is not running after reconfigure.

# guix system reconfigure /etc/config.scm
...console-font-tty3 console-font-tty4 console-font-tty5 console-font-tty6 virtual-terminal dbus-system elogind upower-daemon wpa-supplicant xorg-server networking...
To complete the upgrade, run 'herd restart SERVICE' to stop,
upgrade, and restart each service that was not automatically restarted.

During boot I saw: rfkill: WLAN soft blocked, and after start up I've made sure of it:
# rfkill list
0: ideapad_wlan: Wireless LAN
    Soft blocked: yes
    Hard blocked: no
1: phy0: Wireless LAN
    Soft blocked: yes
    Hard blocked: no
2: ideapad_bluetooth: Bluetooth
    Soft blocked: yes
    Hard blocked: no

I do not know how to overcome this soft blocking of wlan. In other distribution I added to blacklist ideapad_laptop and it worked, but here when I add ideapad_laptop to modprobe blacklist, ifconfig does not see any interface but only phy0. I think this soft blocking happens because I have bluetooth and wifi and may be they conflicts using one driver? I want to disable bluetooth at all, but lines in my config do not help:
(remove (lambda (service) (eq? (service-kind service) bluetooth-service))

Let me know if there is any way to solve all these troubles?
