Hi, |
| 2 |
|
| 3 |
I have an up-to-date ~amd64 GenToo installation with has been |
| 4 |
built on a current AMD64 (Phenom II) machine where I used |
| 5 |
-mtune=native in etc/make.conf since I didn't think of the case |
| 6 |
that I would need to port this system to a somewhat older Opteron |
| 7 |
based machine (still AMD64) |
| 8 |
|
| 9 |
But after cloning the system, some fundamental utilities die of |
| 10 |
an illegal instruction. So I have to rebuild GenToo nearly |
| 11 |
from scratch. emerge -e world doesn't work. |
| 12 |
|
| 13 |
So, what is a reasonably fast method? |
| 14 |
|
| 15 |
I'd like to keep |
| 16 |
/etc |
| 17 |
/usr/portage except /usr/portage/packages |
| 18 |
/var/lib/portage |
| 19 |
|
| 20 |
Is there a fast method e.g. by using the Gentoo based |
| 21 |
SystemRescueCD to reinstall a very basic system, such that |
| 22 |
I can do emerge -e world. |
| 23 |
It looks as if the gcc tool-chain is intact since I could |
| 24 |
compile a kernel without any problem. |
| 25 |
But some utilities, e.g. find, die of an illegal instruction. |
| 26 |
|
| 27 |
Many thanks for any hints saving me a couple of hours work, |
| 28 |
|

Helmut. |
