Chad Smith (chad.smith) wrote : cloud-config: cloud_dir setting not honored globalling by cloud-init

Changes to /etc/cloud/cloud.cfg system_info: paths: cloud_dir setting is not honored globally in cloud-init. Some paths continue to hardcode /var/lib/cloud paths to certain operations.

Affects cloud-init version 22.2

[Test Plan]
