Title: Systemd removes OpenVPN IP addresses Status in systemd package in Ubuntu: New Bug description: This is probably related to, but not a duplicate of, bug 1815101. Running root@third:/home/leroy# lsb_release -rd Description: Ubuntu 18.04.2 LTS Release: 18.04 Systemd version: root@third:/home/leroy# apt-cache policy systemd systemd: Installed: 237-3ubuntu10.21 Candidate: 237-3ubuntu10.21 Version table: *** 237-3ubuntu10.21 500 500 http://us.archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages 100 /var/lib/dpkg/status 237-3ubuntu10.19 500 500 http://security.ubuntu.com/ubuntu bionic-security/main amd64 Packages 237-3ubuntu10 500 500 http://us.archive.ubuntu.com/ubuntu bionic/main amd64 Packages I expected the OpenVPN IP addresses to remain, instead they were removed, the physical NIC address remained, process: Start OpenVPN with systemctl start openvpn@<config-name> (in this situation, two instances).
