This is an element which will run a script on first boot to rename
`/boot/loader/entries` filenames to match the new value of
`/etc/machine-id`. This is required for `grub2-mkconfig` calls to
incorporate existing values in the boot loader entry files.
It only runs when first-boot criteria is met, such as when
`uninitialized` is written to `/etc/machine-id`
