The simplified story is that guix builds and installs software in an immutable store, with unfriendly looking paths such as `/gnu/store/123verylonghash-networkmanager-4.3.1/`. These are then symlinked into a so-called profile, which can be activated which means that the right environment variables are set so systems can actually use softare installed in the store. NM and each nm vpn plugin has their very own 'unfriendly' store path as well. We have services in guix that are akin to a daemon along with its configuration. It is at this point we decide which vpn plugins to enable, and only at this point where we know which paths should be visible to nm in order to properly 'see' the vpn plugins. > > At that point, can you not patch NetworkManager source to look at the > right place?

To summarize and directly address your point; there is indeed *one* location where we put all of our vpn plugins, but this location is only known after building each of nm and the selected vpn plugins. This is a consequence of the Guix software model. As such, directly patching the source or having a configure option would not help us here. NB, we could hardcode a location such as `/usr/lib/NetworkManager/VPN` as well, but this would require a hack that would not be acceptable for inclusion in `Guix proper'. > > Thomas Thanks, Jelle _______________________________________________ networkmanager-list mailing list [email protected] https://mail.gnome.org/mailman/listinfo/networkmanager-list
