The deployment of the source date epoch file had a race condition where any task attempting to read from the file would race with creation of the sstate archive for the do_deploy_source_date_epoch task. The creation of the sstate archive requires moving the directory to a temporary location, then moving it back. This means that the file disappears for a short period of time, which will cause a failure if any other task is running and trying to open the file to get the current source date epoch.
The solution is to copy the source date epoch file to a separate directory when deploying so the file never disappears. When the file is restored from sstate, it is moved to the correct location after being extracted.
