[2.4] PXE boot unconditionally updates interface VLAN

[Mike Pontillo]

When a machine boots from the network, MAAS remembers which rack controller interface observed the PXE boot, and uses that information to determine which VLAN the interface booted from.

This information is not accurate if a DHCP relay is in use, or if a non-MAAS DHCP server tells its clients to PXE boot from MAAS.

MAAS should only update the VLAN of a machine seen during a network boot if the machine has not yet been commissioned. After commissioning, the network configuration is expected to be explicitly set by the MAAS administrator.

What if someone picks the machine up and moves it or the cables are changed? Shouldn't MAAS handle those changes automatically, especially as we push more towards the networking be completely automated.

To me this seems like its going backwards.

[Andres Rodriguez (andreserl)]

I think that updating the inteface VLAN should be prevented only when MAAS is *not* managing DHCP and the user is using an external DHCP server (and obviously, the interface is set to DHCP).
