systemd_networkd role for OpenStack-Ansible¶

# Cleanup all known network interfaces. When this option is enabled the role

# Prefix for all networkd files created by this role. This prefix allows
# deployers to set specific file names reducing the chance of a collision
# and simplifies the network interface file cleanup operation should it ever
# be needed. By default, the prefix is "general" however this can be changed
# to meet the needs of the deployer.
