Android uses a completely different linker/loader. You cannot run
Android directly from your davinci filesystem. Very important shared
libraries will not be in the correct place on the filesystem. Just
changing env variables is not good enough. In this setup, you are going
to have to use chroot:
chroot /filesystem /init (or /sbin/init for me)
Read up on chroot. It essentially will make /filesystem the / directory
for whatever command you invoke.
