Re: %desktop-services #:select service alsa-service-type - unbound variable

Thank you for your response, Pierre Neidhardt!
I tried NetworkManager on GuixSD and have no troubles with it. But I dislike NM 
cause it stores wifi password as it is, but wpa_supplicant saves hash only. Of 
course, I want delete NetworkManager cause I want to control network by myself 
without such a monster. Further I will configure dnsmasq and I know NM pretty 
cool linked with it, but no.

As it is now, I tried to move config to /etc/wpa_supplicant/wpa_supplicant.conf 
and reboot. So the service wpa-supplicant was running

# herd status wpa-supplicant
Status of wpa-supplicant:
  It is started.
  Running value is 324.
  It is enabled.
  Provides (wpa-supplicant).
  Requires (user-processes dbus-system loopback).
  Conflicts with ().
  Will be respawned.

But I could not connect to network running `dhclient -v wlp2s0` so I think I do 
not know how get wpa-supplicant service to use my config by default.

Your piece of code grews like this:

# cat /etc/config.scm
...
  (services (cons* (xfce-desktop-service)
                    (remove (lambda (service)
                     (eq? (service-kind service) network-manager-service-type))
                    %desktop-services)

As I can understand guix will compile entire system with such config.scm from 
sources, cause such configuration is not presented in GuixSD servers, am I 
right?

This construction is hard understandable for me. 
https://www.scheme.com/tspl4/start.html#./start:h5 did not help this time. I 
want also to delete polkitd, avahi, cups, but I have troubles from start 
learning Scheme:
I tried 2 Scheme compilers: MIT-Scheme and Chicken, but their behavior is quite 
different even with 'print' function. MIT-Scheme gives errors on `(print x)` 
and `print x`. http://0x0.st/sxhA.png  But (lambda (service) ...) is very hard.
