Introduction
- Sometimes we need to boot Linux without HDD e.g. if you want to experiment with HDD encryption, enable/disable it without causing damage to your data. For such cases we need a LiveCD which doesn't mount HDD at boot.
Creating Initial System with debootstrap
apt-get install debootstrap mkdir livecd debootstrap --arch powerpc squeeze /root/livecd http://ftp.us.debian.org/debian # Grab a beer and reverse some PS3 stuff in the meantime :) # Enter chroot environment mount -t proc none /root/livecd/proc mount --rbind /dev /root/livecd/dev LANG=C chroot /root/livecd /bin/bash export TERM=xterm-color echo "debian" > /etc/hostname dpkg-reconfigure tzdata # Configure network interfaces cat /etc/network/interfaces --- auto lo iface lo inet loopback allow-hotplug eth0 iface eth0 inet dhcp allow-hotplug wlan0 iface wlan0 inet dhcp wpa-ssid ssid wpa-psk psk -EOF- # Configure APT cat /etc/apt/sources.list --- deb http://ftp.us.debian.org/debian squeeze main deb-src http://ftp.us.debian.org/debian squeeze main deb http://security.debian.org squeeze/updates main deb-src http://security.debian.org squeeze/updates main -EOF- aptitude update aptitude install locales dpkg-reconfigure locales aptitude install console-data dpkg-reconfigure console-data tasksel install standard aptitude install binutils gcc make git vim openssh-server sudo wpasupplicant libssl-dev aptitude install gcc-spu g++-spu newlib-spu spu-tools update-rc.d ssh defaults aptitude clean
Initramfs
Linux 3 Kernel
- We need a Linux 3 kernel with overlayfs support so we could create a tmpfs over our read-only base filesystem.
- At the moment overlayfs is not supported on Linux 3.5 so it leaves us with Linux 3.4 which doesn't really matter because all my Linux 3 drivers are supported on Linux 3.4 just fine.
- Furthermore, we want to compile PS3 HDD driver as module because in this case we can easily change HDD region flags.
