Are there any special details about your set configuration that we might
need to consider? The following strace command seems to show that
load_emerge_config uses the correct world file when the ROOT variable is
set:

$ ROOT=/mnt/gentoo strace python -c 'from _emerge.actions import
load_emerge_config;
load_emerge_config().target_config.setconfig.getSetAtoms("world")' 2>&1
| grep world
