Before:

[📦 org.gnome.Recipes flatpak-xdg-utils]$ ./_build/src/flatpak-spawn --share-pids true
--share-pids not supported by host portal

After:

[📦 org.gnome.Recipes flatpak-xdg-utils]$ ./_build/src/flatpak-spawn --share-pids true
--share-pids not supported by host portal

This feature requires Flatpak to be using a bubblewrap (bwrap) executable
that is not setuid root.

The non-setuid version of bubblewrap requires a kernel that allows
unprivileged users to create new user namespaces.
