# 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. Shared by every BootAMI
# system image (eks-node, rds-postgres): all are dual-NIC, so the data ENI is
# DHCP'd here for the Ec2 IMDS datasource to 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 — without it the in-guest agent cannot reach the control
# plane at all. 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).
