26 days agoIf you are new to Linux I think it makes sense to use systemd. It’s the default for a reason. All major distros use it for a reason. It’s only a really small minority of very vocal people who are against it.
If Debian and Fedora and Ubuntu and All the enterprise linuxes use the same thing, I think that says something.
Despite claims to the contrary systemd is substantially faster and easier to use than its predecessor.
It’s simpler and easier to use. Take a look at these examples. Service files are so so much easier to use and are much more robust than hundred line bash scripts.
Systemd:
[Unit]
Description=OpenVPN tunnel for %i
After=network-online.target
Wants=network-online.target
[Service]
ExecStart=/usr/sbin/openvpn --config /etc/openvpn/%i.conf
Restart=on-failure
[Install]
WantedBy=multi-user.target
Sysvinit
#!/bin/sh
### BEGIN INIT INFO

# Required-Stop: $network $remote_fs
# Default-Start: 2 3 4 5

for conf in "$CONFIG_DIR"/*.conf; do
[ -e "$conf" ] || continue
inst=$(basename "$conf" .conf)

if start-stop-daemon --start --quiet --background \

--exec "$DAEMON" -- --daemon ovpn-$inst --writepid "$pidfile" --config "$conf"; then
log_progress_msg "$inst"

log_warning_msg "Failed to start $inst"
fi
done
log_end_msg 0
}
stop() {
log_daemon_msg "Stopping $DESC"
for pid in "$PID_DIR"/*.pid; do
[ -e "$pid" ] || continue
inst=$(basename "$pid" .pid)
if start-stop-daemon --stop --quiet --pidfile "$pid"; then
rm -f "$pid"
log_progress_msg "$inst"
else
log_warning_msg "Failed to stop $inst"
fi
done
log_end_msg 0
}
status() {
for conf in "$CONFIG_DIR"/*.conf; do
[ -e "$conf" ] || continue
inst=$(basename "$conf" .conf)
pidfile="$PID_DIR/$inst.pid"
if [ -e "$pidfile" ] && kill -0 "$(cat "$pidfile" 2>/dev/null)" 2>/dev/null; then
echo "$inst is running (pid $(cat "$pidfile"))"
else
echo "$inst is not running"
fi

}
case "$1" in
start) start ;;
stop) stop ;;
restart) stop; start ;;

exit 0
Out of curiosity how is life without systemd better? What does it taste like?
