 ### Create GPT partition labels
 
 For each partition involved, create the partition label from these components:
 
 - The partition number (e.g. /dev/nvme0n**1**, or /dev/sda**1**)
-- The parent type in your disko config (value of `disko.device.disk.example.type = "disk";`)
-- The parent name in your disko config (attribute name of `disko.devices.disk.example`, so `example` in this example)
-- The partition name in your disko config (attribute name of `disko.devices.disk.content.partitions.*.name`)

 ### Recovering from mistake
 
-If you made a mistake here, your system will be waiting for devices to appear, and then run into timeouts. You can easily recover from this, since rebooting into an old generation will still use the legacy way of numbering of partitions.
