Some users when auto-provisioning, power down the system once they see the auto-provisioning service exit successfully. However, in some cases this can cause the files created from the provisioning process to not be fully written to disk, resulting in 0-byte files upon next boot.
Therefore, add some explicit syncs to improve this behavior. Also make use of a temp directory to improve the overall atomicity of the process.
