I remember hearing this paper presented at USENIX 1998, in New Orleans. IIRC, the most interesting part of the presentation was a slide titled "Is UNIX portable?" Miller said, of course it is, I ported it! But then he showed a chart with the number of lines of code in the distribution and the number he had to replace for the Interdata mini, and the proportion was quite large! His punch line was that yes, he had ported UNIX, but it wasn't quite so clear that you could call it portable.
