# Alpine 3.19 replaced legacy iptables with nftables based implementation. We
# can't be certain that all hosts that run Tailscale containers currently
# suppport nftables, so link back to legacy for backwards compatibility reasons.
# TODO(irbekrm): add some way how to determine if we still run on nodes that
# don't support nftables, so that we can eventually remove these symlinks.
