Ok, I cut a dvd, and the same thing happened. It boots from an original dvd just fine locally so I know its my authoring that failed. How would I know if its a mkisofs or mksquashfs issue?
Your mksquashfs command is in build-cd.sh, and it runs w/o additional commands, yet mine was ~20megs smaller? Not sure that's an issue? I also don't know at which point the unpacking completes so that if I got tossed into a bbox prompt could that happen before the unpacking?
I am hoping its just how I authored it, my mkisofs was as follows:
mkisofs -o ../LinuxMCE-DVD-DL-i386-rc2_custom.iso -b isolinux/isolinux.bin -c isolinux/boot.cat \
-no-emul-boot -boot-load-size 4 -boot-info-table -r -V "Joes LMCE-Core" -cache-inodes -J \
-joliet-long -l -iso-level 4 -relaxed-filenames -allow-lowercase -ldot .
