This requires a bunch of METALOG mangling to include the files we inject into the tree. The mkisoimages.sh and make-memstick.sh scripts are now called with the current directory inside the tree so that the relative paths in the METALOG match up with the current directory. The scripts do not require this when not using a METALOG, but for simplicity we always do so. The Makefile mangles the real METALOG created from the install, as those files are shared across all uses of the tree, but the shell scripts create a temporary copy of the METALOG that they mangle as their tree modifications are specific to that image. We also need to pass -D to makefs to turn any duplicate METALOG entry errors into warnings, as we have many (harmless) instances of those. Whilst dvd1.iso should work, the !NOPKG code will need more work to support this. All media will also lack mergemaster and etcupdate trees, since more work is needed to add -DNO_ROOT modes to them. Users of install media built this way will have to manually bootstrap them. Reviewed by: brooks, gjb Differential Revision: https://reviews.freebsd.org/D33999

# 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.
