Fun with custom Ubuntu ISO's

Apparently, when you are making an ISO the genisoimage command does not like it when you issue try to use a list of files and subdirectories as your argument, however, works fine when you present a single argument that is a directory name.

So let us say you are in the directory where you have configured your custom distro and you now want to pack it as a bootable ISO. It appears the safest syntax to use is something like this:

sudo genisoimage -no-emul-boot -boot-load-size 4 -boot-info-table  -b isolinux/isolinux.bin -c isolinux/boot.cat -V "my image" -o ../my_image.iso .

As a result, you get the image packed into my_image.iso one level above.

Additionally, here is a nice link to a manual on how to modify your distro step by step:
