Hello Damian,
Thanks for your swift reply.
I was currently starting the motion service the 'classical' way using
/etc/init.d/motion, not systemctl as in your [1] and [2].
Triggered by your reply to change umask for the daemon only (not per user or
all non-privileged logins) I stumbled over
https://serverfault.com/questions/166176/ways-to-set-umask-on-ubuntu-for-daemon-processes
<https://serverfault.com/questions/166176/ways-to-set-umask-on-ubuntu-for-daemon-processes>
in which the last reply ads the --umask option to /etc/init.d/motion as
follows:
if start-stop-daemon --start --oknodo --exec $DAEMON -b --chuid motion
--umask 002 ; then
in the start) case. After making this change and restarting motion, starting
with an empty directory (no Log.txt, sub-directories or video files), this does
solve the issue for files: they are now created with 664 instead of 644
permission. But any created directory still has the 755 instead of the expected
775 permission, as if directory permissions do not follow the umask setting.
Then to follow your exact suggestion using systemctl: I disabled the daemon in
/etc/default/motion and /etc/motion/motion.conf. I switched to systemctl by
copying motion.service to /etc/systemd/system/motion.service, adding UMask=0002
in [Service] section, setting autostart of motion with 'sudo systemctl enable
motion'. Finally cleaned all files and restarted. That all worked as expected,
but again the files get permission 664 (good), but directories still will be
created with 755 (bad)...
So I can not yet delete files inside the directories, unless I add group write
permission to these directories...
Any idea why that could be ?
Thanks again !

Oh well,
for directories you are out of luck. The motion-internal mycreate_path()
function uses 0750.

Correction, 0755 not 0750, but that does not change things.
