We also set up .control/strategy/build and .control/strategy/seed files with values of local and stage3 respectively. These files define the building strategy Metro will use when we build pentium4 funtoo-current stages. With a build strategy of local, Metro will source its seed stage from funtoo-current pentium4, the current directory. And with a seed strategy of stage3, Metro will use a stage3 as a seed, and use this seed to build a new stage1, stage2 and stage3.
