# This script will rename the hard drive name to match the computer name.
# It should be used after the Computer Hostname task.
# Do not use `/bin/hostname -s` because that is not always the computer name.

# Change History:
# 2015/12/03:	Get the computer name in all caps. Also set the computer name to the all caps name.	
# 2016/08/16:	Added bless command to fix problem with Mac losing startup disk after reboot.
# 2016/08/31:	Specify local host name based on computer name. We found several Macs getting their local host name truncated.
