Here we will remaster the gentoo minimal cd and inject a funtoo stage3 or undead usb squashfs image into it.
setup
user $ mkdir ~/livecdtmp user $ mv gentoo-minimal.iso ~/livecdtmp user $ cd ~/livecdtmp user $ mkdir mnt user $ sudo mount -o loop gentoo-minimal.iso mnt user $ mkdir extract-cd user $ sudo rsync --exclude=/image.squashfs -a mnt/ extract-cd
decompress
- the edit directory is the uncompressed squashfs archive, and can be chrooted into if we were to go that route.
user $ sudo unsquashfs mnt/image.squashfs user $ sudo mv squashfs-root edit
merge
- merge in our gnome stage3 with our gentoo boot disk:
user $ sudo tar --numeric-owner --xattrs --xattrs-include='*' -xpf funtoo-gnome-stage3.tar.xz -C ~/livecdtmp/editfuntoo
- or from a squashfs image.
user $ sudo unsquashfs -f -d ~/livecdtmp/editfuntoo /mnt/filesystem.squashfs
load modules
- merge the live cd's kernel modules with our stage3 root:
user $ sudo cp -r edit/lib/modules/5.10.27-gentoo-x86_64 editfuntoo/lib/modules/
compress
user $ sudo mksquashfs editfuntoo extract-cd/image.squashfs
burn
- now we are ready to cd into extract-cd & generate the iso image again:
user $ cd extract-cd user $ 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 . user $ sudo isohybrid --uefi ../funtoo-live.iso
