Arch Linux

/etc/rc.d/portmap writes an empty pidfile instead if one with portmap's pid:

---SNIP---
PID=`pidof -o %PPID /sbin/portmap`
case "$1" in
start)
stat_busy "Starting Portmap"
[ -z "$PID" ] && /sbin/portmap
if [ $? -gt 0 ]; then
stat_fail
else
echo $PID > /var/run/portmap.pid
add_daemon portmap
stat_done
fi
;;
---SNIP---

When $PID get set, portmap isn't running and it isn't re-set after portmap is started. Thus "echo $PID > ..." writes nothing more than a newline.

A better solution would be to either replace "echo $PID" with "pidof -o %PPID /sbin/portmap", and/or set the $PID variable from that file.

The reason I report this as a bug even though the start-stop-script works by itself is that server monitoring applications like Monit require proper pidfiles.
