 This is built in src/distrib/amd64/cdroms/bootcd and it includes
 only minimum boot files for rescue.

 This is built in src/distrib/amd64/installimage-bios via
 build.sh install-image. It looks prepared for some BIOS machines
 that don't work with "Hybrid MBR boot code handover structure"

 This is built in src/distrib/amd64/installimage via
 build.sh install-image. See PR/45153 and PR/45155.
 
 These install images are built by Makefiles in src/distrib/common/bootimage.

 This is built in src/distrib/amd64/cdrom via build.sh iso-image.

 Same as amd64 (no UEFI version though).
 
 > These are all qualitatively different from the arm64/armv7/riscv/octeon images like https://nycdn.netbsd.org/pub/NetBSD-daily/HEAD/202403200640Z/evbarm-aarch64/binary/gzimg/arm64.img.gz and https://nycdn.netbsd.org/pub/NetBSD-daily/HEAD/202403200640Z/evbmips-mips64eb/binary/gzimg/octeon.img.gz.
 
 There is another install image build structure.
 I'm not sure if there were any PRs or discussions about this,
 but these images are created via src/distrib/utils/embedded.
 
 Makefiles in src/distrib/utils/embedded are invoked
 via "build.sh release" -> "make release" in src/etc
 -> "post_md_post" target in src/etc/etc.${MACHINE}/Makefile.inc
 -> "__mkimage" target in src/etc/etc.${MACHINE}/Makefile.inc
 -> src/distrib/utils/embedded/mkimage script using
    src/distrib/utils/embedded/conf/${h}.conf
 
 These are also includes /etc/rc.d/resize_root to expand partition size.
