the whole reason to not run as root isn’t related to noexec, not sure where that came from; the noexec warning has been around for at least a year, and is just that - a warning (not an error). It’s to ensure that under ChromeOS, the script is downloaded to a place that the user has write permission. The chronos/crosh user has write permission in their home directory; the root user does not. It also allows the same exact command to be used under ChromeOS and Linux.
