# Managed by the mesh (module systemd-networkd). Replaced on every push; edit
# the catalogue instead.
#
# This machine's uplink is systemd-networkd's, and the mesh asks one thing of it
# here (novox/hq ADR 0117): leave the private network's interface alone. mesh0
# is the mesh's; the mesh brings it up and configures it itself. The mesh never
# declares a link, an address, a route, a wireless network or its credentials,
# nor a network file for any of this machine's own interfaces — those are
# the operator's, and the link they make is the only channel the mesh reaches
# this machine over.
#
# 00-: networkd applies the first .network file, in alphanumeric order across
# every directory, that matches an interface, and ignores every later one even
# if it matches too (systemd.network(5), [Match]). A catch-all of the operator's
# — Name=*, Type=ether, a file with no [Match] at all — sorted before
# this one would claim mesh0 first. 00 sorts before every numbered prefix the
# man page recommends.
#
# Unmanaged=yes: "no attempts are made to bring up or configure matching links,
# equivalent to when there are no matching network files" (systemd.network(5),
# [Link], since 233). A match that ends the search, and does nothing else.
#
# No DNS setting, because none is needed: networkd never writes
# /etc/resolv.conf. What it learns from a lease it hands only to
# systemd-resolved, which the mesh does not run (novox/hq ADR 0196). So this
# module declares the resolver file itself, beside this one, listing the
# mesh's resolvers (novox/hq ADR 0223).
#
# The service is reloaded when this file changes, never restarted: a restart
# drops the links networkd holds, this machine's channel to the mesh among them.
