The Mushroom Memorial Page

The Mushroom project came to a tangible end when the Sun file server known as was switched off in the summer of 1995.

To commemorate this event, members of the group and friends gathered for a ceremonial power-down. While the system was live, multi-user, and still on the net, the following command was issued as root, overwriting the contents of the hard disk:

        yes 'This disk intentionally left blank. ' | dd of=/dev/xy0c
The machine continued to run for about 30 minutes (!). The only evidence of anything being awry during this time was that the destination of each symbolic link contained a fragment of the string being written!

After 30 mins, the machine came to a sudden and final stop, and was pronounced dead.

Interested onlookers, awaiting the end, watch the system console (running top) while the fatal command executes.

The machine was commissioned on 24 Feb 1987 (as a Sun 3/180), and was finally decommisioned on 18 Aug 1995, by which time it was Sun 4/180.
