Introduce $BASEBITSDIR for clarity and in order to avoid repeating this mistake in the future. Fixing this ensures that we pick up the newly built boot code and loader native to the target, which is especially relevant when cross-building release images. - It is pointless to specify an endianess for ISO 9660 images so strip that.

# 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 [-b] image-label image-name base-bits-dir [extra-bits-dir]
|
|
#
|
|
# Where -b is passed if the ISO image should be made "bootable" by
|
|
# whatever standards this architecture supports (may be unsupported),
|
|
# image-label is the ISO image label, image-name is the filename of the
|
|
# resulting ISO image, base-bits-dir contains the image contents and
|
|
# extra-bits-dir, if provided, contains additional files to be merged
|
|
# into base-bits-dir as part of making the image.
