Generate tftp

To create the kernel and the initrd image, create the source directory, place the gentoo-minimal image, the slackware squashfs-tool package, the script provides an automatic mode (in the "auto" config file), it starts the decompression of the necessary components from gentoo-minimal, dissects and packs into a new image. In manual mode, run generate.sh (create the tmp directory) then prepare.sh (install the squashfs-tools package), then mkautostart.sh (Add the necessary items in .bashrc), at the end of pack_image.sh, it will create gentoo and initramfs.gz
