Hello! Today I had a time to configure guix. I've deleted network-manager-service-type for to use wpa_supplicant + dhcp, but guix gives the error:

# guix system reconfigure /etc/config.scm
guix system: error: service 'dhcpv4-daemon' requires 'networking', which is not provided by any service

# cat /etc/config.scm

I am an anti-fan of NetworkManager. I need wpa_supplicant with dhcp, I try this config with dhcpcd. But it needs networking service. Please, how to add networking service without adding network-manager-service-type?
