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 126.96.36.199 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?
