<code>$NAME</code> part of this by concatenating the driver type with the name <code>$NAME</code> part of this by concatenating the driver type with the id
of the guest, and then escaping any systemd reserved characters. and truncated name of the guest, and then escaping any systemd reserved
characters.
So for a guest <code>demo</code> running under the <code>lxc</code> driver, So for a guest <code>demo</code> running under the <code>lxc</code> driver,
we get a <code>$NAME</code> of <code>lxc-demo</code> which when escaped is we get a <code>$NAME</code> of <code>lxc-12345-demo</code> which when escaped
<code>lxc\x2ddemo</code>. So the complete scope name is <code>machine-lxc\x2ddemo.scope</code>. is <code>lxc\x2d12345\x2ddemo</code>. So the complete scope name is
<code>machine-lxc\x2d12345\x2ddemo.scope</code>.
The scope names map directly to the cgroup directory names. The scope names map directly to the cgroup directory names.
