Howdy!

Yeah, let’s just keep /run/current-system & co.

Yes, it’s a good idea to include ~/.icons and
~/.guix-profile/share/icons (I thought that XCURSOR_PATH did not take
override the default, which includes ~/.icons.)

I think we should set XCURSOR_PATH via
‘session-environment-service-type’ like in the patch I posted.  I find
it marginally nicer than setting it in /etc/profile because that way it
remains close to ‘gnome-service-type’; we need to do the same in
‘xfce-service-type’ though.  WDYT?

Then, eventually, we can add XCURSOR_PATH as a search path definition of
‘libxcursor’, but due to bug 20255, it won’t be effective here; so
that’ll be a mostly cosmetic change.

Does that make sense?

Anyway, glad we have a fix.  :-)
