[comp.unix.questions] Historical fact ?

   I really wonder why root inode is 2. In the old ages it was 1 (CACM 74).
When did it change ? I'd like to give an answer to my students this week !

I seem to recall that it changed between 6th and 7th Edition,
i.e. around 1977.  I think inode 1 was reserved for chaining
bad blocks onto, but I don't recall that being implemented.
