       - systemd stage 1 does not support `boot.initrd.postDeviceCommands`. Instead, create systemd services using the `boot.initrd.systemd.services` options, which has an API matching the stage 2 `systemd.services` options. Refer to `bootup(7)`, specifically the sections on "Bootup in the Initrd" and "System Manager Bootup", for information about when various units happen, and order services accordingly.
