So I have been working on this for a while trying to get things to cross compile, and i got this to compile it is the Source and the program runs on the nook. Next we will have to write our new init.rc to mount our own os. Someone will have to help me with some research, but I just thought you should know.

Here are the files:
2nd-init.tar

To recomile with the NDK use the following command:
Code: 
/home/<user>/Downloads/android-ndk-r7/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-gcc --sysroot=/home/<user>/Downloads/android-ndk-r7/platforms/android-14/arch-arm/ 2nd-init.c
(Thanks to Indirect)

GOOD LUCK

Hmm, if only another developer told you how to cross compile. Oh wait! Haha, congrats Loglud. :)

Jeeze idk, i completely forgot about this thread until you guys posted on it. I never did to much testing. This was mostly done in concurrence with the Kexec-Mod since i had the toolchain up and running. If i remember correctly it did generate the second init file, don't know if it ever loaded it, but i can work on it some more if people want. I was hoping some one would point me in the direction they needed me to go with this.

However the problem is it requires kexec mod.

Sorry, but you're wrong.
From this source use the Hijack method. This mean you can instal a custom rom, but you can't replace the kernel or bootloader.
From the source:
It's also important to remember that 2nd-init does NOT unlock the bootloader, nor does it allow you to run a custom kernel. It simply allows us to utilize the kernel that is there for our own means

That method is good enough to run CM9 and it's relative simple to port.

The kexec method is something different, but better: is a system call that enables you to load and boot into another kernel from the currently running kernel.
kexec performs the function of the boot loader from within the kernel.... essentially a hijack to allow us to call another kernel as a function of the stock one, allowing us to bypass the locked bootloader.

Someone has had success with this method

See this twitter feed:
http://twitter.com/androidnemith

@AndroidNemith just have seen your photo with the CWM on the Nook tablet. How did you do that since the Bootloader is locked ?

@PetePetePete1 Hijacking . Same way moto defy and others are doing it. Right now i am kicking it manually looking for a better way now.

@AndroidNemith can you show your current state XDA developers, because they are still searching for a method to get a custom bootloader

@PetePetePete1 It's not quite ready and i got distracted by NookColor bits. If you want to see what i am doing look at the Moto Defy CM

I take no credit for finding this, as I haven't been talking with @AndroidNemith
