That _is_ a missing piece of the dracut/initramfs toolchain: we need
something in dracut that scans what files have been included from the
buildhost, finds what rpm they belong to and writes down the NEVRA
into a file that goes _into_ the initramfs.

Right now, it is impossible to trace back the origin of an arbitrary
initramfs built by dracut. Unless you find the build host (and it
hasn't changed!).

At OLPC we've had a few incidents of "where the hell did you build
this initramfs?" and "how can I respin this initramfs with only this
patch applied, no other changes whatsoever?".

cheers,
