Ok, that helps somewhat. But now start-stop-daemon allways starts the
script.

----------------------------------------------------------------------
#!/bin/sh
#
# debian-mirror cron script
#
# This will start the debian-mirror script to update the local debian
# mirror, unless its still running.

set -e

test -x /usr/sbin/debian-mirror || exit 0

touch /var/run/debian-mirror.pid
chown mirror.nogroup /var/run/debian-mirror.pid

touch /var/log/debian-mirror.log
chown mirror.nogroup /var/log/debian-mirror.log

start-stop-daemon -S -m -c mirror:nogroup -u mirror -p /var/run/debian-mirror.pid -x /usr/sbin/debian-mirror >>/var/log/debian-mirror.log &
----------------------------------------------------------------------

Thats how I start the script know and "ps aux" shows:

mirror   20123  0.5  0.4  2076 1044 pts/3    S    02:07   0:00 sh -e /usr/sbin/debian-mirror
mirror   20125  0.2  0.2  1516  640 pts/3    S    02:07   0:00 rsync -rlpt --partial -v --progress --exclude Packages --delete ftp.de.debian.org :debian/dists/sid/Contents-i386.gz /mnt/raid/rsync-mirror/debian/dists/sid/

and cat /var/run/debian-mirror.pid:
20123

But running the script again starts a new instance:

mirror   20123  0.0  0.4  2076 1044 pts/3    S    02:07   0:00 sh -e /usr/sbin/debian-mirror
mirror   20135  0.1  0.4  2076 1044 pts/3    S    02:07   0:00 sh -e /usr/sbin/debian-mirror
mirror   20137  0.0  0.2  1516  696 pts/3    S    02:07   0:00 rsync -rlpt --partial -v --progress --exclude Packages --delete ftp.de.debian.org :debian/dists/sid/Contents-i386.gz /mnt/raid/rsync-mirror/debian/dists/sid/
mirror   20143  0.0  0.2  1516  668 pts/3    S    02:08   0:00 rsync -rlpt --partial -v --progress --exclude Packages --delete ftp.de.debian.org :debian-non-US/dists/sid/non-US/Contents-i386.gz /mnt/raid/rsync-mirror/debian/non-US/dists/sid/non-US/

and cat /var/run/debian-mirror.pid:
20135



So what am I doing wrong there?
