You are installing a kernel with an initrd image │
│ │
│ You are attempting to install an initrd kernel image (version 2.6.17) on │
│ a machine currently running kernel version 2.6.15-26-powerpc. │
│ │
│ I have been unable to find a suitable tool for generating initrd images │
│ (I looked at the list "mkinitramfs-kpkg mkinitrd.yaird") This will break │
│ the installation, unless such tools are also being installed right now │
│ in the same run. (This means, one from the following list │
│ initramfs-tools (>= 0.53) | yaird (>= 0.1.11) | linux-initramfs-tool,)
