Hi folks, the Debian Policy Manual still talks about "run levels" and "init.d scripts" on https://www.debian.org/doc/debian-policy/ch-opersys.html#s-sysvinit . No word about systemd and others.
What is the right way to restart a service from the postinst script for Stretch and newer? Reason for asking is: opensmtpd died once too often when it got restarted via invoke-rc.d from a postinst script on my desktop PC. Every helpful comment is highly appreciated Harri
