Yes, this does not include a kernel but only Essential:yes packages, apt and their dependencies. > What can I do to build Debian image with kernel for imx6? Using Isar or > something? I'm not familiar with imx6 and which kernel image you need for that but I can tell you how you can create a bootable qemu image for amd64 and maybe by replacing linux-image-amd64 by the correct kernel this might work for you. Though maybe you boot with uboot or the like and thus more work might be needed. $ mmdebstrap --variant=apt --include=linux-image-amd64 unstable debian-unstable.tar $ cat << END > extlinux.conf > default linux > timeout 0 > > label linux > kernel /vmlinuz > append initrd=/initrd.img root=/dev/sda1 rw console=ttyS0 END $ guestfish -N debian-unstable.img=disk:2G -- \ part-disk /dev/sda mbr : \ part-set-bootable /dev/sda 1 true : \ mkfs ext2 /dev/sda1 : mount /dev/sda1 / : \ tar-in debian-unstable.tar / : \ extlinux / : \ copy-in extlinux.conf / $ qemu-img convert -O qcow2 debian-unstable.img debian-unstable.qcow2 Thanks! cheers, josch
