The HTML rendition of the paper is much improved now, thanks to Naoki Hamada. Incidentally, I also associate the term "deadstart" with CDC/Cray. Maybe London or Reiser had previous association with that world. On the other hand, in really early Unix, the "cold boot" paper tape recreated everything on the disk. Really cold, just like the "operating system conversion" section of L&R, or for that matter the corresponding section of the one by me and Johnson about the Interdata work. Dennis
