Description=StartOS graceful restart
# Reboot/kexec counterpart of startos-shutdown.service (see its comment).
DefaultDependencies=no
# Conflicts= selects reboot (not poweroff). The ExecStop graceful teardown
# (start-cli server restart -> startd shutdown_all -> per-container Exit RPC +
# lxc-stop) must run while startd and the containers are still up, exactly like a
# manual `start-cli server restart`. A unit ordered After=X is stopped *before* X
# on shutdown, so these two hold until the teardown has finished:
#   startd.service                     - startd must be alive to service the RPC
#   lxc.service / lxc-monitord.service  - lxc.service's ExecStop is `lxc-containers
#                                        stop`; unordered, it kills the container
#                                        before the Exit RPC ("ungracefully dropped")
# Ordering only; Conflicts= stays the sole reboot-vs-poweroff selector.
