 |
|
Hi
is there a way do an easy downgrade from AMD64 to normal 32bit?
An don't like the ~amd64 keyword trouble anymore, so I want the downgrade.
With easy I mean easyer then a bare metal install of the system.

Moving down to 32bit without re-installing would be impossible. Everything you have is compiled 64bit and none of it would run with a 32bit kernel.
If you want to drop back to 32bit, you absolutely have to re-install

You can do it without a full reinstall:
1) Set up a 32bit chroot environment on its own partition.
2) Install a full 32bit Gentoo system in the chroot environment.
3) Reconfigure Grub to boot from the 32bit partition rather than the 64bit partition.
4) Reboot.
At this point, you'll have a running 32bit system, a partition containing the old 64bit system, and your home directory wherever you left it. Cleaning up is left as an exercise for the reader. |

Hi
in this case I will switch to sabayon and only compile the important packages by my own.
I just don't have time for one week compiling...
thank you for your help

one week?
a night. Maybe.
Or is 32bit really that slow?

At no point do you have a computer that lacks a fully-functional operating system, and the user data is always on the hard drive, so you can't exactly describe it as a full reinstall. |

During installing you can make stage4 (and 5, 6...)
In my opinion is not worth to stay on amd64. Not because it makes problems but it gives nothing.

You have a fully functional system if you install from knopix of ubuntu, but it's still a whole installation. Using another installation of Gentoo doesn't make it different than chrooting from any other linux. You start from scratch, chrooting from another Gentoo and you have to go through all the steps in the handbook. So, I fail to see your point.
And the user data is completely irrelevant, your mp3 collection has nothing to do with reinstalling your OS.
And to answer to the original poster: yes, in one way or another, the only way is to reinstall. |
