While hanging around lca07 it was mentioned how bandwidth hungry Gentoo is. |

Given a lot of the world is still on dialup this could increase the potential userbase for Gentoo. |

As such the project idea is Automated Xdelta Generation. |
| 6 |
|
| 7 |
principles: |
| 8 |
no manual generation of xdeltas by gentoo devs |
| 9 |
simple user usage (FEATURES=xdelta) |
| 10 |
avoiding digesting problems |
| 11 |
remain compatible with existing ebuilds |
| 12 |
|
| 13 |
user interface: |
| 14 |
|
| 15 |
FEATURES=xdelta emerge ~sys-kernel/gentoo-sources-2.6.20 |
| 16 |
found /usr/portage/distfiles/linux-2.6.19.tar.bz2 |
| 17 |
fetching linux-2.6.19_xdelta_2.6.20.xdelta |
| 18 |
generating linux-2.6.20.tar |
| 19 |
digest /usr/portage/distfiles/linux-2.6.20.tar matches |
| 20 |
storing /usr/portage/distfiles/linux-2.6.20.tar.bz2 |
| 21 |
(more fetching) |
| 22 |
unpacking |

FEATURES=xdelta emerge ~sys-kernel/hardened-sources-2.6.20 |
| 28 |
found /usr/portage/distfiles/linux-2.6.20.tar.bz2 |
| 29 |
digest mismatch - checking linux-2.6.20.tar |
| 30 |
digest good - assuming it was xdelta generated |

I'm thinking xdeltas that gets generated on the staging server and some portage support so facilitate a minimal download. |

Note: i haven't looked at previous xdelta portage patches from years ago. |
