[[User:Drobbins|Daniel Robbins]] maintains [[Metro]], so it comes pre-configured to successfully build [[Funtoo Linux]] releases. Before reading further, you might want to customize some basic settings like the number of concurrent jobs to fit your hardware's capabilities or the directory to use for produced stage archives. This is accomplished by editing <tt>~/.metro</tt> which is the [[Metro]]'s master configuration file.
Please note that <code>path/install</code> must point to where metro was installed. Point <code>path/distfiles</code> to where your distfiles reside. Also set <code>path/mirror/owner</code> and <code>path/mirror/group</code> to the owner and group of all the files that will be written to the build repository directory, which by default (as per the configuration file) is at <code>/home/mirror/funtoo</code>.
