   | 15143   | Remove obsolete backing up of ROOTPATH via PORTAGE_ROOTPATH. |
   | zmedico |                                                              |

   | 15145   | In save_ebuild_env(), preserve all ebuild phases in any case |
   | zmedico | since excluding the already executed ones from               |
   |         | environment.bz2 doesn't save much space, and it's possible   |
   |         | that someone would want to look at them later.               |

   | 15147   | Remove stray echo.                                           |
   | zmedico |                                                              |

   | 15149   | Bug #297364 - Only set EAPI conditional PATH once after      |
   | zmedico | sourcing the ebuild (when the EAPI is first known) rather    |
   |         | than for each phase.                                         |
