Hi, i improved the test script by adding two more manipulation modes: - "mbr_only" produces an EFI compliant ISO without GPT, HFS+, APM. - "original" lets the xorriso arguments pass unchanged.
The mode can be chosen by the environment variable MKRESCUE_SED_MODE Default mode is "mjg": ESP in MBR+GPT+APM, HFS+ in APM. Other environment variables for parametrization are MKRESCUE_SED_PARTNO MKRESCUE_SED_PROTECTIVE MKRESCUE_SED_DEBUG MKRESCUE_SED_XORRISO MKRESCUE_SED_XORRISO_ARGS Read the first half of the script for explanations. The script may now be stored anywhere. If it does not find its neighboring "../../xorriso/xorriso", then it uses "xorriso" by default. By MKRESCUE_SED_XORRISO one can address the xorriso binary explicitely. Download from http://libburnia-project.org/browser/libisoburn/trunk/frontend/grub-mkrescue-sed.sh?format=txt If GNU xorriso -version says Version timestamp : 2015.12.27.150821 and one wants to test -DLibisofs_mjg_boot_for_grub2, then one should overwrite the file xorriso-1.4.3/libisofs/system_area.c by the file version that is downloadable as http://bazaar.launchpad.net/~libburnia-team/libisofs/scdbackup/download/1301/system_area.c-20081019135100-i5wqmczu54lzyabt-1/system_area.c and run "make". This keeps the results of mode "original" compliant with EFI even if -DLibisofs_mjg_boot_for_grub2 was in effect at compile time. The result of "original" still is influenced by the fact that -DLibisofs_mjg_boot_for_grub2 prevents writing of gap filling partition table entries. ----------------------------------------------------------------- Examples: wget http://libburnia-project.org/browser/libisoburn/trunk/frontend/grub-mkrescue-sed.sh?format=txt mv grub-mkrescue-sed.sh?format=txt grub-mkrescue-sed.sh chmod u+x grub-mkrescue-sed.sh export MKRESCUE_SED_XORRISO=$HOME/xorriso-1.4.3/xorriso/xorriso export MKRESCUE_SED_MODE=mjg export MKRESCUE_SED_PARTNO=2 grub-mkrescue -o output.iso minimal --xorriso=./grub-mkrescue-sed.sh unset MKRESCUE_SED_PARTNO export MKRESCUE_SED_MODE=mbr_only export MKRESCUE_SED_PROTECTIVE=no grub-mkrescue -o output.iso minimal --xorriso=./grub-mkrescue-sed.sh unset MKRESCUE_SED_PROTECTIVE export MKRESCUE_SED_MODE=original grub-mkrescue -o output.iso minimal --xorriso=./grub-mkrescue-sed.sh Inspect results by: $MKRESCUE_SED_XORRISO -hfsplus on -indev output.iso \ -report_system_area plain -report_el_torito plain ----------------------------------------------------------------- Have a nice day :) Thomas _______________________________________________ Bug-grub mailing list [email protected] https://lists.gnu.org/mailman/listinfo/bug-grub
