Comment 11 for bug 1611082

Interestingly the packaging should be trying to make some directory changes:

       # 5. adjust file and directory permissions
       if ! dpkg-statoverride --list $SERVER_HOME >/dev/null
       then
           chown $SERVER_USER:$SERVER_GROUP $SERVER_HOME
           chmod u=rwx,g=rx,o= $SERVER_HOME
       fi
       if ! dpkg-statoverride --list /var/log/ceph >/dev/null
       then
           chown -R $SERVER_USER:$SERVER_GROUP /var/log/ceph
           # members of group ceph can log here, but cannot remove
           # others' files. non-members cannot read any logs.
           chmod u=rwx,g=rwxs,o=t /var/log/ceph
       fi

       # 6. fix /var/run/ceph
       if [ -d /var/run/ceph ]; then
           chown $SERVER_USER:$SERVER_GROUP /var/run/ceph
       fi
