Thomas Petazzoni - Feb. 6, 2013, 9:49 p.m.
The order of the solutions to customize the root filesystem is
changed: we now mention the post-build script mechanism *before* the
custom root filesystem skeleton mechanism, because the former is
preferred over the latter.

In addition to this, we give a few more details about direct
customization of the root filesystem in output/target, and about the
custom target skeleton solution.
