MariaDB 10.1+ includes `PrivateDevices=true` in its systemd unit files to
add extra security around mount namespaces for MariaDB. While this is
useful when running MariaDB on a bare metal host with other services, it
is less useful when MariaDB is already in a container with its own
namespaces. In addition, LXC 2.0.8 presents `/dev/ptmx` as a bind mount
within the container and systemd 219 (on CentOS 7) cannot make an
additional bind mount of `/dev/ptmx` when `PrivateDevices` is enabled.
Deployers can `galera_disable_privatedevices` to `yes` to set
`PrivateDevices=false` in the systemd unit file for MariaDB on CentOS 7.
The default is `no`, which keeps the default systemd unit file settings
from the MariaDB package.
