Hi Harald, is it possible that you are running some kind of security protection like apparmor with some old profile loaded, or selinux or you have edited the default systemd unit and added Private*=yes or other security options or something like that (check /etc/systemd/, what does systemctl status mariadb says, etc.).
This: Process: 3119 ExecStartPre=/usr/bin/install -m 755 -o mysql -g root -d /var/run/mysqld (code=exited, status=226/NAMESPACE) has not much to do with mariadb-10.1 itself, but it looks like overzealous security settings in the system or in the systemd service file. Or perhaps you are running in some restricted container/lxc?
