# Minimal chrony NTP server for the lab boot LAN. Diskless workstations get this

# host as their time source via DHCP option 42 (dnsmasq), so they never reach the
|

# public NTP pool (no workstation egress). Config is bind-mounted from
|
|
# chrony.conf in docker-compose.yml. Build our own so the version is pinned.
