ah, uh, sorry i forgot to add that.

but note that "leaving" is not entirely precise here. It's invoked after the tpm device pops up, but we do not wait any longer than that. So it might not be a the beginning of the initrd (since tpm might take a bit to pop up), but it's definitely more the beginning than the end, since we do not explicitly delay this.
