Yes, with a few privisos.  I hope you don't think these are too
onerous, but from a libguestfs point of view they are vital:

- It would have to work with Fedora (dracut) and Debian

- It would need to not slow down boot at all.  ie.
  'time guestfish -a /dev/null run' should not be affected

- It shouldn't make the boot any more risky/buggy than it is
  currently.  A low bar because our boot is already quite buggy,
  but let's not make things worse ...

Rich.
