Adopt recent changes in FreeBSD to increase the ESP size after loader has grown beyond 800kB and restore partition order after mkimg changes. While here, label the ESP "EFISYS" to match FreeBSD. Jira: NAS-110869

# 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
|
|
