Hi Guix,
I avoided doing this when fixing up GDM because it seemed a little
ham-fisted (clumsy). However, I think it is better than all the ink
that would be spilled on help-guix without it.
In short, the point is to make sure that D-Bus services included in a
user’s profile can be found and started by the session bus. This means
that if you are using GDM and install “evolution-data-server” and
“gnome-calendar” (for example), the session bus will be able to start
all of the services that GNOME Calendar needs to function correctly.
There are a handful of major GNOME applications that need this.
Furthermore, I think we should add “evolution-data-server” as a
propagated input for packages that require it. This way, things like
“guix install evolution” will just work the way one expects.
Is it okay to assume that “.guix-profile” is the user’s profile like
this? If it isn’t okay in general, is it okay enough for now?

Subject: [PATCH] services: gdm: Include user profile in D-Bus paths.
This partially addresses <https://bugs.gnu.org/35267>.
* gnu/services/xorg.scm (dbus-daemon-wrapper): When '$HOME' is set,
include directories from '$HOME/.guix-profile' in the search paths of
the D-Bus daemon.

The e-ink, you mean.

Sounds like a worthy goal. :-)

In this particular case, I’d say it’s OK.
Do we have any other option on the table anyway?

Same thing with a few comment explaining what you wrote above would be
great.
LGTM!
Thanks,

We could run D-Bus from a login shell. The reason I didn’t opt for this
is that GDM launches D-Bus from a stripped-down environment. It’s not
clear to me if there’s a reason for doing so, or if it was just the way
the code came together. Essentially, I’m trying to be conservative.
I’m still holding out hope that a future “user sessions” feature in Guix
will make all of these hacks go away. :)

I pushed a nicer version (following the style of the “xinitrc” code)
with a long comment as dcb3a0fe0a086b4762a721e9b1da64826d5160d0.
Thanks for the review!

As we accumulate the hacks, motivation rises! :-)
