Thank you for the report. Have you been able to update the ebuild by simple renaming?
Nope, that did not work. The ebuild points to an old location at https://inxi.googlecode.com/svn/tarballs/. According to https://github.com/smxi/inxi/blob/tarballs/README.txt they only support the current version upstream. The location of the current tarball is: https://github.com/smxi/inxi/raw/master/inxi.tar.gz
prepared ebuild for inxi-2.3.0 https://github.com/jonasstein/jstein-overlay/tree/master/sys-apps/inxi

Added your overlay manually in my /etc/portage/repos.conf/layman.conf but was not able to sync (app-portage/layman-2.3.0-r1): !!! Repository 'jstein-overlay' is missing masters attribute in '/usr/local/overlays/jstein-overlay/metadata/layout.conf' !!! Set 'masters = gentoo' in this file for future compatibility
your question is about the usage of layman/overlays. You will get the best support on IRC and the forums about this. Let us use this bug ticket strictly for the ebuild bump request.
