I don’t know if this applies to all distributions, but at least in Ubuntu, 
the GNOME on Wayland and KDE on Wayland desktop sessions are started 
without a shell being invoked at any point, so ~/.profile and related files 
don’t get evaluated.

In KDE, the way to define environment variables that will be set in the 
Wayland session is to put a shell script in ~/.config/plasma-workspace/env/.

I hadn’t figured out how to do it in GNOME when I briefly searched for it. 
This systemd override file seems to be the solution.

By reading the manual (or cookbook).  Updating package descriptions
with a list of quirky annoyances on foreign distros is surely overkill.
We don't even put CVEs in there, instead describing those to ignore in
a property.

I'll write up an appropriate entry once I've figured out how I want to
word it.  However, I'd like to also state for the record, that a lack
of such is not really a bug in Guix.  Applications packaged in Guix not
only honour the environment variables they're supposed to honour, they
sometimes even have more of them.  The trouble comes from implicit
defaults being assumed (and therefore not set) by the foreign distro.

Cheers

What "property" is that?  I am interested in knowing about CVE in Guix
packages.

Kind regards,

I have defined TZDIR on ~/.profile and so far it's working.  Let's see
if it continues to work well.

And how will other users know how to fix the problem?  Will Guix's
manual be updated?  There could also be a message in the Emacs package
description.

Regards,
  Jorge

In my personal experience, the value did not get sourced correctly when
I put it into .bash_profile.  I do not know about .profile, but I guess
you'll run into similar issues.  In either case, evaluation order is
something you might want to consider.

Now the advantage of doing this at all is that you get finer control
over which environment variables are set when.  It doesn't really make
sense to e.g. set the font path when you're in a terminal.  The
disadvantage is that it's obscure and brittle -- the value TZDIR will
only be correctly set inside GNOME in this example, for other desktop
environments you'd have to copy the definitions.  What if you're
launching just a terminal session?  Don't ask me.

I'm pretty sure there's some systemd file where you can put these
instead, but in the years of using it up to encountering Guix I've
never needed such a thing and now that I do use Guix, I'm quite content
with Shepherd as my PID 1.  I still remember some of systemd's major
features that I miss from shepherd, like socket activation or the
ability to control GNOME Shell at all, but ask me about some incredibly
mundane task like setting a timer and I'll have to consult a manual on
that.

Cheers

Hello.  So the solution to the bug is for the user to manually write the
file ~/.config/systemd/user/gnome-shell-x11.service.d/override.conf ?

I would like to know a little more about that.  What is the advantage of
specifying the environment variables on that file instead of ~/.profile?

Kind regards,
  Jorge
