Thanks for correcting my nomenclature, Albert. I too was wanting to use |
| 29 |
oldconfig for upgrading my kernel from .20 to .21, but decided not to |
| 30 |
after reading the recommendation of the Gentoo Kernel Upgrade Guide, the |
| 31 |
relevant portion of which I have pasted below. Perhaps this applied only |
| 32 |
to the specific example used. |
| 33 |
|
| 34 |
My purpose for pasting this into this discussion is three-fold: to show |
| 35 |
why I said what I did, to hopefully dispel the notion that I merely made |
| 36 |
this all up, and to discuss the relevance of the pasted text itself. |
| 37 |
|
| 38 |
I apologize for being off-topic and hope that Mick finds himself a |
| 39 |
working kernel config soon. :) |

10. Advanced: Using your old kernel .config to configure a new one |
| 51 |
|
| 52 |
It is sometimes possible to save time by re-using the configuration file |
| 53 |
from your old kernel when configuring the new one. Note that this is |
| 54 |
generally unsafe -- too many changes between every kernel release for |
| 55 |
this to be a reliable upgrade path. |
| 56 |
|
| 57 |
The only situation where this is appropriate is when upgrading from one |
| 58 |
Gentoo kernel revision to another. For example, the changes made between |
| 59 |
gentoo-sources-2.6.9-r1 and gentoo-sources-2.6.9-r2 will be very small, |
| 60 |
so it is usually OK to use the following method. However, it is not |
| 61 |
appropriate to use it in the example used throughout this document: |
| 62 |
upgrading from 2.6.8 to 2.6.9. Too many changes between the official |
| 63 |
releases, and the method described below does not display enough context |
| 64 |
to the user, often resulting in the user running into problems because |
| 65 |
they disabled options that they really didn't want to. |
