[Bacula-users] bacula-sd.conf: permission denied

[<kra...@fr...>]

Hey there,

I'm having a problem on a virtualized Debian 9 server where i want to install bacula (7.4.4)
I'm not able to start the SD, while FD and DIR are OK

When I try to start it with _systemd start bacula-sd_, i'm getting the following

Oct  9 14:11:29  bacula-sd[6539]: Config error: Cannot open config file "/etc/bacula/bacula-sd.conf": Permission denied
Oct  9 14:11:29  bacula-sd[6539]: 09-Oct 14:11 bacula-sd: ERROR TERMINATION at parse_conf.c:919
Oct  9 14:11:29  bacula-sd[6539]: Config error: Cannot open config file "/etc/bacula/bacula-sd.conf": Permission denied
Oct  9 14:11:29  systemd[1]: bacula-sd.service: Main process exited, code=exited, status=1/FAILURE

I thought permissions issues, but it seems not.
I've tried to 
- apt-get install --reinstall bacula-sd, same problem (so with default permissions)
- remove bacula-sd.conf : same problem (weird, i guess i should have a "no such file or directory" ?)
- start with /etc/init.d/bacula-sd : same problem
- check permissions in /etc/bacula + /var/lib/bacula + /run/bacula : same problem
- set an unix password to my bacula user (that belongs to the "tape" group of course) to try to ssh login and go|see /etc/bacula/bacula-sd.conf, worked perfectly
- start it with -- sh -x /etc/init.d/bacula-sd start -- but am not able to see any problem

The only thing that works is if I manually start the SD from CLI -- /usr/sbin/bacula-sd -f -c /etc/bacula/bacula-sd.conf -- that confirms me it neither related to a typo mistake from bacula-sd.conf nor an LTO problem (communication problem). Once started this way, i'm able to "status sd" in bconsole.

.... any hint appreciated !
