From: Fabian Klemp <fabian.kl...@axino-group.com>
openvpn only provides options to update a pid file but not to check it
for running processes. Consecutive issued start commands therefore lead
to multiple running processes with the same configurations, which is the
origin of all kinds of problems of which unnecessary resource usage is the
least.
Using start-stop-daemon the pid file is inspected for running processes
before start.
