I was wondering. Why not build on work that has been done using chroot environment to put linux on top of (or coexist with) android.

As many have pointed out the project over the past six months seem to come to a stand still with very little reason given. Well there any many reason but the main being that the developers on the project simply had no free time to work on this, money dried up and I (the lead developer) had to step back to work more on paid projects and keep the bills paid!
