inode 1

[nickolas.landsberg]

If memory serves correctly, the first version of Unix I worked with
(V5) used inode 1 for the root inode of mounted file systems.  Somewhere
in the time frame of 1978 or so, the root inode was redefined as 2
and inode 1 was "reserved for future use."  (The future has not yet
arrived, I guess.)  Can anyone with a better memory pin down exactly
which version of Unix changed the magic 1 to a magic 2?
