Hi guix,
Consider the following home configuration:
(use-modules (gnu home) (gnu packages) (gnu home services)
(gnu services) (guix gexp) (gnu home services shells))
(define formula-of-the-day
;; TODO: add some more formulae, randomise
"$US dollar/=E2=82=ACeuro =3D 1.11")
(home-environment
(packages '())
(services
(list (simple-service 'extra-environment-variables
home-environment-variables-service-type
`(("formula of the (reconfiguration) day" . ,formul=
a-of-the-day))))))
Now start a container with this configuration with "guix home container":
$ guix home container home-configuration.scm
[start output block]

To investigate, I took a look at 'setup-environment':
[lots of exports]
export formula of the (reconfiguration) day=3D$US dollar/=E2=82=ACeuro =
=3D 1.11
There are at least two issues here:
* The variable 'formula of the (reconfiguration) day' was not quoted.
I don't know how to do this in bash though, if it is even possible
at all. If it turns out not to be possible, I'd prefer that to
be mentioned by a nice error message, e.g. "environment variable
names may not contain FOOs" or "environment variable names must
consist of BARs".
* The value '$US dollar/=E2=82=ACeuro' was not quoted, so bash would
expand $US (to the empty string, since $US is not defined).
Greetings,
Maxime.
