Description

Currently, the bootstrap script shuts down the existing Agent before attempting anything else. This is a problem, as any bug/malfunction that terminates the execution before the new Agent is set up risks to leave the old Agent stopped, so the machine becomes unresponsive. The logic needs to account for potential failures and only restart the Agent after all the bits have been deployed and the configuration has been properly set.
