It was 1 in 6th edition, 2 in 7th edition.  No, I don't have a better
memory, just more manuals :-)

The 7th edition manual says "I-node 2 is reserved for the root
directory of the file system, but no other i-number has a built-in
meaning".  I can't see any mention of the use of inode 1.

Next question: when did i-nodes become inodes?
