DHCP pool mode requires dhcpcd-base (/usr/sbin/dhcpcd) to obtain
leases from the router. Added to Makefile install-system, setup.sh
binary installer, and source-install docs.
Closes: mulga-753
- All guides: OVN setup before admin init (consistent ordering)
- Single-node + source-install: Replace --external-bridge/--external-iface
with auto-detection + --wan-bridge/--wan-iface/--macvlan options
- Multi-node: Simplify examples (auto-detect WAN bridge), show override
options in prose
- setup.sh: Update "next steps" to match single-node guide, add
--wan-bridge/--macvlan guidance for physical NIC setups
Part of mulga-742.
