#            serves DHCP/TFTP/HTTP boot/SMB. ignore-carrier: the address
#            is put on (and kept) without link, so a switch that is off
#            or a cable pulled at boot does not leave dnsmasq, Samba and
#            Apache without {{ pxe_server_ip }} (networkd
#            ConfigureWithoutCarrier= + IgnoreCarrierLoss=).
#   ge-corp  GE corporate network, DHCP client (SSH + webapp 9009, updates).

# The imaging NIC pinned by MAC, every other wired port a DHCP client:
#   pxe-lan  imaging LAN, matched by MAC and given a stable name. Static,
#            no gateway, no DNS. The ONLY NIC that serves DHCP/TFTP/HTTP
#            boot/SMB. ignore-carrier: the address is put on (and kept)

#   zz-en, zz-eth  every other wired port: DHCP client, so the GE cable
#            can go into any of them, at install or later. No set-name.
#            networkd applies the first matching .network file in name
#            order: 10-netplan-pxe-lan sorts before 10-netplan-zz-*, and
#            {{ pxe_nic_name }} does not look like en*/eth* (the playbook
#            checks), so the imaging NIC never falls into these. dnsmasq
#            never serves them (interface= pins it to {{ pxe_nic_name }}),
#            and a drop-in makes them ignore offers from {{ pxe_server_ip }}.
