Dear Maintainer, we are trying to install new KVM virtual machines with Debian 12 and here is what happens after reboot with sysvinit and apt install: postsrsd: Generating initial /etc/postsrsd.secret Starting Postfix Sender Rewriting Scheme daemon: postsrsdpostsrsd: Cannot write PID: /var/run/postsrsd.pid failed! invoke-rc.d: initscript postsrsd, action "start" failed. Looks like some issue with Apparmor. It works with systemd.
