... and I want to stay an happy gentoo user for next years, however, my current computer is aging and I'm planning to change it in the next weeks to come (In fact, I'm waiting UT3 to be out for Linux to change my whole hardware  )
And, therefore, rise the question of "how the hell can I migrate my current gentoo from my old computer to my new" ??
I guess that dd -if /old_computer -of /new_computer by plugging the old disk in the new computer wont gives nice results ?
I'd rather recompile everything from scratch because :
- I want to optimize all the programs for my new arch
- I want to clean all orphan packages once for all
I'm already happy with the package selection I've made so far on my computer, and I'd like the same for my new computer.
What tips for migrating could you suggest ?
I know that I must copy /home.
There are some files, especially in /etc/ that I want to save, especially fstab, world file, grub.conf, bashrc.
Probably by following the gentoo installation guide, I can either copy from old computer or recreate from scratch the needed files.
The world file gives me headache : simply transfer it to the new computer and type emerge --sync and then emerge --update --world --newuse --deep ??
Thx for any suggestions as I didn't find any relevant things either in gentoo documentation or in the forums. |

No, I have a Pentium4 and I'd like a Core2 Quad 6600.
However, running through the forums, I've found that topic : https://forums.gentoo.org/viewtopic-t-618527.html
I think this topic has already been answered there. |

Save:- old world file
- old /etc
- old home directory
This is probably 98% of the information you need. You can emerge all your old stuff on the new system with the command: | Code: | | # emerge `cat old-word` |
where old-world is a copy of your world file from the old system. I found there were many packages I didn't want on the new system so I just removed them from the old-world file.
I migrated from a dying laptop to a new desktop about a year ago and with the information above, it was pretty easy. I also had a lot of my own stuff under /usr/local so you might want to see if there is anything there you want to keep. |

I always copy my old $HOME directory to my new system. It makes a big difference because all my settings are there. It makes me feel right at $HOME.  |
