https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D270393 --- Comment #1 from Ed Maste <emaste@freebsd.org> --- They hybrid ISOs are created by copying the first 32K from a GPT image into= the output image, overwriting the iso9660 system area: 113 # Create a GPT image containing the partitions we need for hybrid boot. 114 hybridfilename=3D$(mktemp /tmp/hybrid.img.XXXXXX) 115 if [ "$(uname -s)" =3D "Linux" ]; then 116 imgsize=3D`stat -c %s "$NAME"` 117 else 118 imgsize=3D`stat -f %z "$NAME"` 119 fi 120 $MKIMG -s gpt \ 121 --capacity $imgsize \ 122 -b "$BASEBITSDIR/boot/pmbr" \ 123 -p freebsd-boot:=3D"$BASEBITSDIR/boot/isoboot" \ 124 $espparam \ 125 -o $hybridfilename 126 127 # Drop the PMBR, GPT, and boot code into the System Area of= the ISO. 128 dd if=3D$hybridfilename of=3D"$NAME" bs=3D32k count=3D1 con= v=3Dnotrunc 129 rm -f $hybridfilename This completely ignores the secondary GPT. We need to copy it as well, enlarging the original ISO image if necessary. --=20 You are receiving this mail because: You are the assignee for the bug.=
