* Avoid waiting for external drive unnecessarily Even though the condition to start hassos-data.service is not met (the file /mnt/overlay/data-move is not there by default), it seems that systemd waits for the dependencies for hassos-data.service. Don't Require or Wants any dependencies which might not be present by default. * Use systemd to wait for partition using partlabel device * Use sfdisk which allows to wipe filesystem signatures Even though we zap the partition table using sgdisk, the file system superblock (which contains the file system label) does survive. This can cause problems when trying to reuse a disk previously already labeled using hassos-data: It might take precendence on next boot over the existing data partition on the eMMC. Make sure to clean all file system signatures using sfdisk.
