Steps to reproduce:
install zabbix-agent2 on a debian without systemd, install satll and never work
Result:
apt cannot install as it block on the startup
case "$1" in start) log_daemon_msg "Starting $DESC" "$NAME" start-stop-daemon $UGDEFS --oknodo --start --pidfile $PID --exec $DAEMON >/dev/null 2>&1
======================================================
should be
case "$1" in start) log_daemon_msg "Starting $DESC" "$NAME" start-stop-daemon $UGDEFS --oknodo --start --background --pidfile $PID --exec $DAEMON >/dev/null 2>&1
