[Bug 1844688] [NEW] "radvd" daemon does not work by default in some containers
Public bug reported:
Since [1], the radvd daemon is spawned with parameter "-u username".
This drops the root privileges and changes the user ID to "username".
In some deployments (e.g. TripleO), the "neutron" user does not have,
inside the L3 agent container, the permissions to modify the host kernel
interfaces (from journal.log):
