I bought an eTrayz NAS time ago. The device is more or less good but it ships with a closed-source custom linux and a bunch of broken web-apps. I wanted to replace the whole system with a raw Debian installation.

I successfully bootstrapped a Lenny Debian into a chroot and I'm able to use use it. However I would like it to be the default system and to boot automatically at login.

The device itself ships with a bundled kernel. I think the kernel is on a dedicated flash memory so I would prefere not to re-flash it.

What do you think is the best way to accomplish it?

Note I also have no idea of how the boot process works on this device. I don't expect it to have Grub or any known bootloader. – knoopx Sep 24 '10 at 13:47
