Hi,
umask doesn't seem to be take into account, here is the output of the debugged init.d script
+ '[' -r /etc/default/collectdmon ']'
+ . /etc/default/collectdmon
++ umask 002
+ case "$1" in
+ start
+ echo -n 'Starting collectd: '
Starting collectd: + '[' -r /etc/collectd.conf ']'
+ daemon collectdmon -P /var/run/collectdmon.pid -c /usr/sbin/collectd -- -C /etc/collectd.conf
...
+ /bin/bash -c 'ulimit -S -c 0 >/dev/null 2>&1 ; collectdmon -P /var/run/collectdmon.pid -c /usr/sbin/collectd -- -C /etc/collectd.conf'
but folder are created in 2755
/var/lib/collectd/rrd2
Access: (2775/drwxrwsr-x) Uid: ( 0/ root) Gid: ( 500/rrdcached)
/var/lib/collectd/rrd2/systest3t
Access: (2755/drwxr-sr-x) Uid: ( 0/ root) Gid: ( 500/rrdcached)
any idea ?
Best regards
