Script: Set Mac OS X Server Serial Number

Continuing with the concept of automated server deployment, here is a small script that changes the serial number in a Mac OS X Sever installation.

A server system that has been deployed via disk imaging or automated deployment systems will boot, but to use the server features, a valid and unique serial number must be entered.  Luckily, Apple provides a command line utility to set the serial number.

The script, as written, is intended for use with The Casper Suite.  Replacing $4 with a static value or using another method of passing a value would be necessary if you are not using The Casper Suite.

# provided in $4 by Casper.
# Run as an "at reboot" script when imaging with Casper, making sure to type
# double-check the serial in the script parameters before imaging.
