Here we will remaster the gentoo minimal cd and inject a funtoo stage3 or undead usb squashfs image into it.
root # mkdir ~/livecdtmp root # mv gentoo-minimal.iso ~/livecdtmp root # cd ~/livecdtmp root # mkdir mnt root # sudo mount -o loop gentoo-minimal.iso mnt root # mkdir extract-cd root # sudo rsync --exclude=/image.squashfs -a mnt/ extract-cd
- the edit directory is the uncompressed squashfs archive, and can be chrooted into if we were to go that route.
root # sudo unsquashfs mnt/image.squashfs root # sudo mv squashfs-root edit
- merge in our gnome stage3 with our gentoo boot disk:
root # tar --numeric-owner --xattrs --xattrs-include='*' -xpf funtoo-gnome-stage3.tar.xz -C ~/livecdtmp/editfuntoo
- or from a squashfs image.
root # sudo unsquashfs -f -d ~/livecdtmp/editfuntoo /mnt/filesystem.squashfs
- merge the live cd's kernel modules with our stage3 root:
root # sudo rsync -a editfuntoo edit
root # sudo mksquashfs edit extract-cd/image.squashfs
- now we are ready to cd into extract-cd & generate the iso image again:
root # cd extract-cd root # sudo xorrisofs -D -r -V "test" -cache-inodes -J -l -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -eltorito-alt-boot -e '/gentoo.efimg' -no-emul-boot -isohybrid-gpt-basdat -o ../funtoo-live.iso . root # sudo isohybrid --uefi ../funtoo-live.iso
