# File name:
|
|
# Description: creates a new link to the IOC booting directory
|
|
# This script works only if yoa are located:
|
|
# - on the boot pc or
|
|
# - on a machine of the bootpc subnet or
|
|
# - on office subnet and want to change boot link on machine.
|
|
# Notes:
|
|
# 1. This script does not jump between different facilities networks!
|
|
# 2. If more IOCs are specified in the command line, they have to boot from
|
|
# unique bootpc and the symbolic link of the specified targetbase will
|
|
# be done for all this IOCs.
