From e7bc48271f4008a01a97b3ae3d961f8bcba518c8 Mon Sep 17 00:00:00 2001

Subject: * Remove redundant lchown() compatibility code since the  
 getattr(os, "lchown", None) call already handles it.

* Simplify the userland detection code in portage.data and add
  a bash version of it to isolated-functions.sh.
