# Opt-in RouterOS + RouterBOOT upgrade to switch_firmware_target.
# Disabled by default (switch_firmware_enabled: false). Upgrades REBOOT the switch,
# so run deliberately with a recovery channel open. Naturally a no-op when the device
# is already at or above the target version (the version guard skips every step).
