Impact

-- K3s cluster goes into an unhealthy state. -- Tenant functionality is impacted.

Changing the hostname via confd does not change the system hostname. Configured hostname is reflected only in the bash and confd prompts. When no hostname is configured, the bash prompt uses a default PS1 prompt.
