# mulga-mgmt-net — boot oneshot that configures a multi-NIC system VM's NICs from
# the fw_cfg netcfg blob before cloud-init crawls IMDS. BootAMI system VMs
# (EKS control plane) are dual-NIC: the data ENI is DHCP'd here so the Ec2 IMDS
# datasource can reach 169.254.169.254 (cloud-init can't pick the right NIC out
# of two on Alpine), and mgmt0's static br-mgmt address is applied. Runs in the
# boot runlevel before cloud-init-local, whose init-local Ec2 crawl otherwise
# burns its whole probe window with no data-NIC route. No-op without a blob.

# cloud-init-local runs the init-local Ec2 datasource crawl; it must see the data
# NIC + IMDS route already up, so this must precede it (not just cloud-init, the
# later network-stage service).
