Hey Guix,
Here is an other “guix deploy” bug: setting a file-system-device field
to a
UUID makes deploy hangs indefinitely. Using a string (eg.: "/dev/sda1")
instead, “guix deploy” succeed. Following is an output showing it
hanging:
--8<---------------cut here---------------start------------->8---
$ 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

The following derivations will be built:

Fixed with 0dd04b9986dd834782c988035569089785a6987d and
04a4af6dd4fbfcfc564eac5eafe647b192ba3a8f. Thanks to Ludovic for the
pointers and both of you for recording the very useful above debugging
session.
Closing,
Maxim
