<p>first glance of the acoming Metro FAQ (RFC)</p> <p><b>New page</b></p><div>i would like to setup also a Metro FAQ. would you please add questions and answers? :-)<br /> --<br /> ferdy<br /> <br /> <br /> 1. what is metro?<br /> Metro is the build system for Funtoo stages. It automates the bootstrapping process.<br /> 2. which is the latest version of metro?<br /> As for today, the raccomanded way to use metro is to clone it from git repository (see Quick Installation Guide)<br /> 3. how can i get metro? How can i configure it? <br /> See Quick Installation Guide<br /> <br /> 4. how i choose the best stage3 for my arch<br /> 5. can i build 32 from 64? and viceversa?<br /> you can build 32 within 64 but not the other way around<br /> 6. can i build any cpu arch from any different cpu arch?<br /> if you use any stage, the CPU of your system needs to support at least<br /> all those instruction of the source or target stage's subarch.<br /> 6. can i build stable from current? and viceversa?</div>
