No. |

It's meant to be a developing profile. Portage does not yet handle ABI-dependant |
| 14 |
dependencies, but we want to work on the 32bit side of things nevertheless. |

All problems related to the profile should block tracker bug #124816. |

Since getting this profile running with a stage3 is rather... "tricky", |
| 23 |
I've put together an experimental stage: |

In other words: It's a great way to mess up your box *very* fast. It won't even |
| 31 |
let you do `emerge -e system` yet. If you feel like digging around in mud, |
| 32 |
contact me off-list and I'll give you some pointers. But don't file bugs without |
| 33 |
having a patch ready, we're simply not there yet. |

Performance doesn't matter in a developing profile, but it should be about |
| 39 |
equally fast for most things. |

No. |
