That sounds good to, and should be easier to achieve. Thanks, Maxim

I'm not convinced that patching XDG_DATA_DIRS is a good solution here. Even if we go forward and implement this for each and every library/application, (it would be reasonably simple to do so for glib and qt at least, but there's many more consumers, including Guix itself), we'd just force users on foreign distros to set up their XDG_DATA_DIRS for us if they e.g. want to have desktop icons available, so they'd quickly encounter the same issue on their own. I see two ways forward for this: First, "ignore it" and just document the behaviour. This isn't just a bug Guix is suffering from, it also affects other third-party package installers like Flatpak and Snap. Since distros increasingly become aware of them, this will soon no longer be an issue for most our users. Second, extend search-paths with a way of enforcing a default value when none is set. This way, Guix will still override XDG_DATA_DIRS, but since $HOME/.local/share:/usr/share is set as the default as per spec, it will do what the distro expected. WDYT?

There are multiple reports about the negative effects of Guix setting variables such as XDG_DATA_DIRS on foreign distributions, that may cause problems a severe as locking users out of their graphical session [0]. In my opinion, we should pursue patching every application/library to use a Guix-specific variant, e.g. GUIX_XDG_DATA_DIRS instead of XDG_DATA_DIRS, to avoid interfering with the host system, as was done for GUIX_PYTHONPATH. This is a big task in itself; we can open more focused/actionable tasks for each environment variable, starting with those causing the most serious issues. Any takers?
