I am deploying 1709 and notice if I schedule a deployment to copy the file to the machine and deploy it later that evening it will not deploy and in the Logs it says "action canceled by user" which is not true No one touched the machine or canceled it.
Also if I stage a patch to a machine and do not deploy it and then the next day I tell it to deploy the patch it markes the old one as a .old file and redeployed the patch.
