[bug#36542] [PATCH 0/6] Fix network-manager vpn plugins

[Jelle Licht]

Hello Guix!

This series should fix the OpenVPN network-manager plugin, as well as
add the network-manager-vpnc plugin. Other vpn plugins should also be
trivial to add.

Please review and test. If someone has a better idea for passing the
NM_OPENVPN_USER et al environment variables to network-manager, I am all
ears.

Is this patch meant to be submitted upstream?  Perhaps it would be worth

This makes sense! I am currently in contact with the people running the
show behind nm, but I do not expect this to be upstreamed quickly.

Nice! I have needed this just recently. I've just applied this series
locally and tested the OpenVPN plugin in gnome and it works like a
charm!

Thanks for working on this!
