At some poing over the last week, the bootx64.efi file has grown past the 800KB threshold, resulting in being unable to copy it to the EFI/BOOT directory. # stat -f %z efiboot.znWo7m 819200 # stat -f %z stand-test.PIEugN/EFI/BOOT/bootx64.efi 842752 The comment in the script that creates the ISOs suggests that 800KB is the maximum allowed for the boot code, however I was able to boot an ISO with a 1024KB boot partition. Additionally, I verified against an ISO from OtherOS, where the boot EFI partition is 2.4MB. Sponsored by: Rubicon Communications, LLC (netgate.com)

# 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.
