# Scenario: a rival network manager active alongside NetworkManager is disabled.
#
# dhcpcd (or systemd-networkd / iwd) running next to NM fights it for the link.
# Break by enabling dhcpcd; the fix disables it, and the chain resets to
# reconnect. Requires dhcpcd installed in the target.

# with no configured uplink that holds, so the rival should be named.
