Try to get Gentoo to provide needed files on the distmirrors #2

This is a discussion with an already existing Bug, probably not to hard to get fix once we have good documentation here on how it could be used. https://bugs.gentoo.org/494300 |

Building with snapcache enabled gives this: |

bootstrap stage2 fails, it was ok first time, but even after clearing all binpkgs still getting this. |

Testing if using this stage3 works around the openmp issue ... FILE=$(wget -q http://distfiles.gentoo.org/releases/amd64/autobuilds/current-stage3-amd64/ -O - | grep -o -E 'stage3-amd64-20\w*\.tar\.(bz2|xz)' | uniq)

netboot targets exists that generates multiple files. The cleanest way would be to split
However this probably makes to much of a disconnect between settings in the stage2 spec files and what would be needed for stage3. - not to mention all the places and documentation that would need updates in regards to livcd stage2/3. in In the end maybe the best, or at least the first solution, would be to simply extract the iso in the upload step instead? |

Have tried to create PoCs to generate PXE files for minimal livecd (amd64), feedback appreciated https://bugs.gentoo.org/494300#c4 |
