Graphic installer doesn't find /mnt/gentoo/make.conf on installation processing (after unpacking the portage snapshot).
Please attach the /var/log/installer.log.failed and /tmp/installprofile.xml
Created attachment 84155 [details] installer.log.failed for #129157
Created attachment 84156 [details] installprofile.xml for #129157 This is only a proof-of-concept.
You specified a portage snapshot URI for your stage tarball URI. Of course it broke :P
Uhhh! Me bad man!
