=Linux 3 Kernel=
 
* We need a Linux 3 kernel with overlayfs support so we could create a tmpfs over our read-only base filesystem.
* Furthermore, we want to compile PS3 HDD driver as module because in this case we can easily change HDD region flags.
 
See my GIT repos:
* http://gitorious.ps3dev.net/ps3linux/kernel-configs
* http://gitorious.ps3dev.net/ps3linux/kernel-patches-34

==BusyBox==
* We need a couple of user-space applications to mount filesystems, load kernel modules and so on.
* And make sure you compile BusyBox without any library dependencies.
* I compiled my BusyBox executable on PS3 Linux but you could cross-compile it too but then you need a complete PowerPC toolchain with libc.

* Tools available on the root filesystem: gcc, spu-gcc, spuisofs, spuldrfs, ps3vuart-tools, ps3sed and all my other PS3 Linux drivers. Everything you need to compile and test various PS3 stuff.

* In case someone still hasn't figured it out yet, password for root is root and password for glevand is glevand :)
* I enabled DHCP on Ethernet.
* You could use WLAN too but for that you have to modify the root filesystem and configure your SSID and PSK in /etc/network/interfaces.
 
==USB==
 
* Your USB drive should be formatted with FAT32 filesystem.
* initramfs-usb.cpio.gz: http://www.multiupload.nl/Y084SCQBL3 (MD5 f94b6aec2e5fbbb26f7d466165071469)
* Create '''debianlive''' directory on your USB drive.
* Put vmlinux-3.6.4 (extract xz archive), initramfs.cpio.gz and root.sfs into this directory.

==CDROM==
=Linux 3 Kernel=


(files seem missing)
* 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.
* initramfs-cdrom.cpio.gz: http://www.multiupload.nl/SA9YK1HFK0 (MD5 f71f8667dc52540136f90a95d7111efc)
* Furthermore, we want to compile PS3 HDD driver as module because in this case we can easily change HDD region flags.
