Description of problem:
since 1.8.16 I cannot run NMCI's openvpn_persistence test but I was with 1.8.14. I juggled with different OpenVPN packages but that was not helpful. 1.8.18 is broken the same way.

The test is here:
https://gitlab.freedesktop.org/NetworkManager/NetworkManager-ci/-/blob/main/features/scenarios/openvpn.feature#L133

Version-Release number of selected component (if applicable):
1.8.16
1.8.18

How reproducible:
always

Steps to Reproduce:
1. git clone https://gitlab.freedesktop.org/NetworkManager/NetworkManager-ci/; cd NetworkManager-ci
2. ./test_run.sh openvpn_persist

Actual results:
fail

Expected results:
no fail
