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>
:
(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?
