yeah very nice one, except that "sudo guix remove package" doesnt work :(

This is how its done in debian/fedora, for e.g this is what debian error 
give if apt needs root rights to delete a package:

"user <at> host:~$ apt remove hexchat
E: Could not open lock file /var/lib/dpkg/lock-frontend - open (13: 
Permission denied)
E: Unable to acquire the dpkg frontend lock 
(/var/lib/dpkg/lock-frontend), are you root?"

This is what it shows in Fedora:

"[user <at> host ~]$ dnf remove wpa-supplicant
Error: This command has to be run with superuser privileges (under the 
root user on most systems)."

But like i said current situation in guix is not about using sudo guix 
or guix alone.
