As Lisa said, the $ROOT environment variable is what you want. I've never |
| 13 |
tried using it though, so I can't vouch for how well it is supported. |

In ebuilds you'll find DEPEND, RDEPEND and PDEPEND. DEPEND is build time |
| 25 |
dependencies and must always be satisfied by packages installed on the "/" |
| 26 |
file system. RDEPEND on the other hand is run-time dependencies and must be |
| 27 |
satisfied on the root filesystem. PDEPEND is a special form of RDEPEND. |

Patches are welcome. Just make sure that separate issues are dealt with in |
| 33 |
separate patches and that they are as concise as possible and include code |
| 34 |
comments to explain things that aren't really obvious. And of course that |
| 35 |
they can be applied to a clean release. |

I must have missed that one too, but I can't seem to find anything from you in |
| 43 |
my archives... |
