<para>A list of permissions attached to an object. An ACL specifies

which users or system processes have access to objects. It also

defines which operations can be performed on specified objects. Each
|

entry in a typical ACL specifies a subject and an operation. For

instance, the ACL entry <code>(Alice, delete)</code> for a file gives

Alice permission to delete the file.</para>

address is shared to another server, the cloud network restrictions

address. You can optionally specify that the target server network

standard heartbeat facilities, such as keepalive, that monitor for

failure and manage IP failover.</para>
