# This script is used by release/Makefile to build the (optional) ISO images
|
|
# for a FreeBSD release. It is considered architecture dependent since each
|
|
# platform has a slightly unique way of making bootable CDs. This script
|
|
# is also allowed to generate any number of images since that is more of
|
|
# publishing decision than anything else.
|
|
#
|
|
# Usage:
|
|
#
|
|
# mkisoimages.sh image-label image-name obj-dir root-dir
|
|
#
|
|
# image-label is the ISO image label
|
|
# image-name is the filename of the resulting ISO image
|
|
# obj-dir is the built object tree
|
|
# root-dir contains the image contents
|
|
