w procedures. (profile-cached-gc-root): Rewrite to include functionality formally in 'single-file-for-caching', but extend to handle package specs. * gnu/packages.scm (cache-is-authoritative?): Export. * guix/transformations.scm (transformation-option-key?): New procedure. * doc/guix.texi (Invoking guix shell): Move '--rebuild-cache' documentation to the bottom, just above '--root'. Explain caching and how these two options relate to that. Ludovic Courtès
