Steves Know Example Mount Script

Example Mount Script

The following are the contents of 2 schell scripts which can be used as is or modified for mounting the build you wish. The important things to consider is the last section, which specifies the machine ("cinta03"), as well as the directory path the build is on ("drive1/421old/install/cd(blahblahbla)").
