I'm trying to modify the installation sequence of Ubuntu Precise. I need add a repository package inside de iso.
I make my own apt repository mirror and add my own packages with
reprepro includedeb. Then I run
mkisofs to make my .iso an include in the final iso. Then I build my customized debian-installer including
iso-scan udeb package. With all of that, I build the fake final iso with:
grub-mkrescue but in the proccess of installation when the iso-scan work take place it can't find the repo.iso file and installation process stops.
I had investigate a lot but I only found things related with debian-installer. I don't know how to do it in Ubuntu Alternate or similar installations.
