Adding file to ISO

[Julio Lajara]

Hey guys, im trying to extract the Clonezilla live ISO, add a file to it and then recreate the ISO.

I used 7zip to extract the ISO and added a 1.7gb file to it. I then used the following to create the ISO from PWD of /tmp/clonezilla:

mkisofs -r -V "Custom Clonezilla" -cache-inodes -J -l -b syslinux/isolinux.bin -c syslinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -o clonezilla-custom.iso /tmp/clonezilla

That generated an ISO fine but it doesnt seem to be usable after putting it on USB drive with dd.

Any thoughts on how I can regenerate this ISO? I need it to boot on a UEFI based system and to be able to run the generation command myself from the CLI and not some other tool. I read some script in the Clonezilla repo that says that there may be size limit issues in one of the tools but not sure if thats relevant here.

Thanks,

Disregard, I was able to get it to work correctly using xorriso:

xorriso -as mkisofs -V "Custom Clonezilla" -o ../clonezilla.iso -isohybrid-mbr /usr/lib/ISOLINUX/isohdpfx.bin -c syslinux/boot.cat -b syslinux/isolinux.bin -no-emul-boot -boot-load-size 4 -boot-info-table -eltorito-alt-boot -e boot/grub/efiboot.img -no-emul-boot -isohybrid-gpt-basdat /tmp/clonezilla

Had to install xorriso and isolinux.
