+# Derive the system hostname from the network at boot.

+# The image carries NO per-host hostname (invariant: no per-host state in the
+# artifact) — /etc/hostname is emptied at build, so the static hostname is unset
+# and the host comes up as "localhost". With hostname-mode=default, NetworkManager
+# sets the *transient* hostname once it has a DHCP lease, in this order:
+#   1. DHCP option 12 (host-name) if the server sends one — the lab dnsmasq's
+#      fleet-namer assigns a creative starship name per MAC, server-side.
+#   2. otherwise a reverse-DNS (PTR) lookup of the leased address.
+# This is already NM's default, but we set it explicitly so a stricter
+# global/STIG config can't silently switch it to "none" and leave hosts unnamed.
