Hello,

When trying to reproduce another “guix deploy” bug for a future bug
report
I stumbled upon this one: it's not possible to deploy as a user
(machine-ssh-configuration-user) different than “root“, even with a
properly configured sudoers file[0]. Deploying with root works when ssh
is
configured with “PermitRootLogin yes”. Following is the backtrace:

Toggle snippet (53 lines)
$ guix deploy -Lmodules systems/hystou-p04.scm
guix deploy: warning: failed to load '(config workstation)':
no code for module (gnu services lightdm)
The following 1 machine will be deployed:
abricot

guix deploy: deploying to abricot...

This isn't the case anymore. I can now use "guix deploy" with a user having
passwordless sudo right, as documented in the manual.
