[ale] What are the major/minor #s for sr0 ?

[James P. Kinney III]

So all scsi devices are labeled /dev/ronjeremya, /dev/ronjeremyb, ...

/dev/clinton would be a parallel port device :) (Hillary AND Monica)
/dev/reagan would be /dev/null (Alzheimer's)
/dev/bush is a serial port (first daddy, then "W")
/dev/GaGov is /dev/zero (it doesn't matter who we get, we're still #49)
