Hi,

How about focusing specifically on XDG_DATA_DIRS, which is the root
cause of the first two bugs you mention?

We could say that installing certain packages will cause
~/.guix-profile/etc/profile to define XDG_DATA_DIRS, that this can
interfere with software installed outside Guix, such as GNOME, and that
we recommend unsetting XDG_DATA_DIRS (is that what we recommend?
breaking Guix-installed packages instead of breaking distro-installed
packages?)?

Thanks,
Ludo’.
