I've noticed an issue with gnap_make where if you try and create a build that has a RELTYPE of something other than the default of 'gnap' (set in common.conf), you can't make a tarball from an ISO image from a previous stage.
Created attachment 98299 [details, diff] Replace /gnap/ with ${RELTYPE} where needed for tarball
The GNAP project has been discontinued, its removal was acknowledged by steev. If you need to, you can contact the Gentoo Embedded project; more information about the Gentoo Embedded project can be found on the following link: http://www.gentoo.org/proj/en/base/embedded/ This removal happens as part of project cleanup by the Gentoo Council's members.
