# Purpose : Keep WinBoat's Windows container from starting at boot. Run by
#           install.sh and on every update (updates.d/75-winboat.sh).
#
# WinBoat's "Auto Start Container" setting is the restart policy in its
# docker-compose.yml, which WinBoat applies to the container. A container that
# restarts on its own runs Windows (8 GB of RAM and 4 cores by default) from
# boot until you stop it, whether or not you use WinBoat. This sets the policy
# back to "no" in the compose file and on the container, which doesn't need
# recreating. WinBoat starts the container when you open it, as before.
