I am trying to reproduce a .iso (of clonezilla), needed a proprietary driver to work. I had to unpack, unsquashfs, add a driver, resquash, re-iso the distribution....
Now, I am trying to re-create a bootable .iso :) An iso that will not be written to DVDs, but to usbs rather, or be booted into xen/kvm/etc...
Every attempt has failed so far... here is the general syntax I am using:
>$ genisoimage -r -v -V "CASPER" -cache-inodes -J -l -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -o ../bootme.iso .
If I download a clonezilla image, and do the following to it :
mount -o loop clonezilla.iso tmp/
mkdir tmp2 && cp -Rf tmp/* tmp2/
run the makemeanewiso.sh from here
Then, the iso does not boot with a xen DomU, but boots just fine if burnt to a DVD :)
Can someone please help me out with mkisofs options to make a good iso?
