It was /etc/update. I used one of these in the Psych department at UCSD. When it started
going weird I shut it down and removed the floppy. As you mentioned, the tracks at the
start of the disk were worn smooth.

It was fun to play with, but as the name implies it was pretty limited.
I recall I got it working on one of those DEC PDT things, with 8" floppies; you had
to turn off "/etc/update" otherwise it wore a groove where inode 1 was, or was
it /dev/tty8? Something like that...
