Early warnings

Once upon the time I was browsing through a book which disassembled the Amiga Kickstart-ROM (well I don't remember it's name but it was long before the very nice Amiga Guru-Buch came out). What I saw there, immediately caught my  attention. If the filesystem on a new mounted filesystem had a specific problem it would try to load a program to fix it. The interesting point was, that it first tried to load from that filesystem! If it couldn't find it there it tried the system-partition. Some hours later I had a floppy that upon inserting it into your Amiga immediately showed a very nice custom Guru-Meditation. I showed this floppy to a friend of mine who was astonished as well because the Amiga had no known feature to automatically start a program upon inserting a floppy. It was very hard to keep it from starting it. Luckily viruses where more a theoretic thing at that time. We had copy protection on our mind. It would be very funny to start the game immediately upon inserting the disk.
