What does this have to do with Obarun?

Why not start with Arch or Obarun. Very few other distros allow so much hacking and choice as arch (and arch-based).

To start an independent and autonomous distro you need to build a few thousand packages first. The wealth of Arch+AUR is nearly unbeatable.

LFS is good exercise but that is about it. Reinventing the wheel is not very sensible.
