One of my colleagues had been itching to get into sys admin for some time,

so last week he was finally sent on a 5-day sys admin course run by HP in

Bracknell..

On the following Sunday, he decided to try out his new found knowledge by

trying to connect and configure a DAT drive on one of our critical test

systems. He connected the cables up okay, and then created the device file

using 'mknod'.

Unfortunately, he gave the device file the same minor & major device numbers

as the root disk; so as soon as he tried to write to this newly installed

'DAT drive', the machine wents tits up with a corrupt root disk....ho hum.
