Hello! I am creating my own config. I've disabled networkmanager-service-type, configured wpa-supplicant (but have not yet configured dhcpcd, cause it needs networking service). 
Guix reconfigures my system normally.

But during boot there is a message: rfkill: WLAN soft blocked
And that is why wpa-supplicant fails:

# reboot
# dhclient -v wlp2s0

# rfkill unblock wifi

# herd restart wpa-supplicant
# dhclient -v wlp2s0


So I need manually unblock wifi and restart wpa-supplicant, but it's not coveinent.

I tried this lines as I've got from here https://superuser.com/questions/819547/how-do-i-stop-rfkill-module-from-hardblocking-my-wifi-without-rfkill-command <https://superuser.com/questions/819547/how-do-i-stop-rfkill-module-from-hardblocking-my-wifi-without-rfkill-command> :


 (kernel-arguments '("modprobe.blacklist=pcspkr,snd_pcsp,wmi,pata_acpi"
                     "modprobe.options.rfkill.master_switch_mode=2"
                     "modprobe.options.rfkill.default_state=1"))

But adding 'wmi,pata_acpi  ' but not helped. If add ideapad_laptop to blacklist, then rfkill does not see interfaces wlan and bluetooth.

# lsmod | grep -e wmi -e acpi
wmi                    32768  1 ideapad_laptop


How to prevent rfkill blocking of wlan?
