Lets see if we can fix the Busybox chroot problem in the above post with this bundle of goodies.

Build notes:

Spoiler:

This is another file blob that you just un-pack with /home of the emulator as the current directory. Puts chroot + 102 other small utilities into /home/bin.

Now the $64 million dollar question - Did it fix the above problem?

Answer: No.


Next step: Install our KeK strace in this copy of the emulator image.

But folks, I've had all the fun I can stand today. Maybe more tomorrow.
