As others have stated, there are likely other ways to do it (try emerge |
| 18 |
--emptytree first, if that doesn't work, try Tres's suggestion, untarring |
| 19 |
the stage tarball over your existing setup, then emerge --emptytree). |
| 20 |
|
| 21 |
However, Nuitari's general method, installing from an existing system into |
| 22 |
new partitions, while still being able to use the existing system while |
| 23 |
you are doing it, works fine. I used it myself, coming from Mandrake. |
| 24 |
|
| 25 |
There is, however, an official document to help, proven to work as it has |
| 26 |
been used by many, so you don't have to worry that Nuitari forgot a step |
| 27 |
or something. =8^) It's called the "Alternative Installation Guide", and |
| 28 |
is actually mentioned in the Gentoo Handbook, Part 1 (Installation), |
| 29 |
Chapter 1 (About), under "What are my Options". |
| 30 |
|
| 31 |
The direct link to the Alternatve Installation Guide is: |

You'll want Chapter 6, Installing Gentoo from an existing Linux |

Basically, that tells you how to use a chroot off of an existing |
| 41 |
installation, describing how this method differs from the normal |
| 42 |
installation method described in the handbook (thus, you still use the |
| 43 |
handbook for most of the installation). During the first part of the |
| 44 |
process, while you are still in the chroot, you can continue doing your |
| 45 |
normal stuff in other sessions outside the chroot, which allows you to |
| 46 |
take all the time you need getting the new installation up and running. |
| 47 |
You can actually stop working on the install and continue using your old |
| 48 |
system for a couple weeks, if you get busy and don't have time to work on |
| 49 |
it, because your old system continues to work as it did before you started |
| 50 |
the new install. |
| 51 |
|
| 52 |
As I said, it only details how this method differs from a normal install, |
| 53 |
so you'll want the regular handbook install section available as well. |
