Hello! We're very glad to inform you that we have just released Hummingbird 1.1.0 beta 1, featuring: SystemV-style init support for Linux update to the latest OpenVPN3-AirVPN and asio libraries Hummingbird is AirVPN's free and open source OpenVPN 3 client based on AirVPN's OpenVPN 3 library fork. Hummingbird is available for: Linux x86-64 Linux ARM 32 (example: Raspbian for Raspberry Pi) Linux ARM 64 macOS (Mojave or higher version required) For a thorough Hummingbird overview please consult https://airvpn.org/hummingbird/readme/ Hummingbird 1.1.0 adds support to Linux systems based on SystemV-style init https://en.wikipedia.org/wiki/Init#SYSV, while the previous versions supported Linux systemd based systems only. Therefore, we gladly achieve compatibility with 35 additional Linux distributions: https://distrowatch.com/search.php?ostype=All&category=All&origin=All&basedon=All&notbasedon=None&desktop=All&architecture=All&package=All&rolling=All&isosize=All&netinstall=All&language=All&defaultinit=SysV&status=Active#simple We think it's important to support Init Freedom: https://devuan.org/os/init-freedom because systemd is POSIX incompatible and because, as the UNIX Veteran Admin collective noticed in 2014 when they announced a Debian fork: This situation prospects a lock in systemd dependencies which is de-facto threatening freedom of development and has serious consequences for Debian, its upstream and its downstream.

Glad it helped. Just in case someone comes across these answer I would like to rectify a couple of things from what I learned lately. It seems I was wrong about hummingbird only changing the network lock at the very beginning. (At least for the current version of hummingbird: 1.0.3). The other day I got some connection problems that led my airvpn connection to a weird state (I posted the logs in the thread where hummingbird 1.0.3 was announced). In addition to the connections state, in the logs I could find that when the system decided to reconnect, DNS and network lock got restored (back to normal) before being set again. This means that any extra rule added with the second method I proposed would get overwritten and lost. I also think that hummingbirds decision of restoring the network lock and DNS even though being for a moment is a risky move from a security point of view. (But I'm not an expert here). The part of the logs that make me think this: ...
