diff docker/base/scripts/sat @ 116:d0a5db5b9bdf

docker: fixed bad stopping: - use exec when it was missing, so the TERM signal is properly catched, and containers can be stopped instead of being killed after 10s - for a unknown reason, exec and su don't handle correctly "$@" with Docker in base.scripts/sat. It's working as expected when launched from withing a running container, but not when launched with "docker run", so a workaround is used with trap and wait
