Description

If an interface is used only for VLANs (e.g. it is not assigned directly) and that interface is removed, the system does not detect this as a problem at boot time and will appear to indicate that the VLANs are up and working when they are not. Attempting to change assignments fails as that part of the code detects the missing the VLAN parent.

The system should fail to boot with an interface assignment prompt when this happens, same as if any other interface is removed. At the very least it should disable/remove affected VLAN interfaces but that would be inconsistent with other behavior.
