MemcacheD sets `PrivateDevices=true` in its systemd unit file to
|
|
add extra security around mount namespaces. While this is useful
|
|
when running MemcacheD on a bare metal host with other services, it
|
|
is less useful when MemcacheD 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 `memcached_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 MemcacheD package.
