How to remove %base-firmware from firmware variable

How to remove %base-firmware from firmware variable

Hello! I saw in Guix manual http://guix.gnu.org/manual/en/guix.html#index-firmware
that there is 'firmware' module in operating-system that is %base-firmware by default.
I want to try to remove 'firmware' module to look if my pc continues to work without it.

Can you please help me?
I use 'remove' procedure in 'services' but really cannot repeat it for 'operating-system'.
I just want to unset 'firmware' or make it totally empty.

Znavko,

Guix's operating-system is a record.  Records are just key-value 
pair collections.  Some keys have default values, but there's no 
need to remove anything when you simply want to replace the 
default.

Pass the empty list as its value:

(operating-system
  ...
  (firmware (list))                     ; or '() if you like that
  ...)

Kind regards,

T G-R

Yes, it works. But only external usb wifi adapter does not work. I use internal now.

$ lsusb
Bus 001 Device 002: ID 0cf3:9271 Qualcomm Atheros Communications AR9271 802.11n
...

$ ifconfig -a | grep Link
enp2s0    Link encap:Ethernet  HWaddr E4:54:E8:BA:20:AC
lo        Link encap:Local Loopback
wlp5s0    Link encap:Ethernet  HWaddr AC:D5:64:52:9C:57


# lspci | grep -i wireles
05:00.0 Network controller: Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter (rev 01)

# lspci -vv -s 05:00.0 | grep driver
	Kernel driver in use: ath9k


I do not know which driver was used for usb wifi adapter, i remember it could connect
with nl80211. Is nl80211 not free?


Can you advice me some powerful usb wifi adapter with free drivers?
