IIRC, RedHat kernels are relatively generic in that they have almost |
| 46 |
everything turned on, and/or build the modules so that they can |
| 47 |
maximize the hardware compatibility. So it is likely that there will |
| 48 |
be tones of stuff that was turned on, or had modules build for it, |
| 49 |
that you didn't need. The same will likely be the case for the gentoo |
| 50 |
kernel. You're best bet is to spend the time on one system going |
| 51 |
through each kernel option (within reason), if you don't know what it |
| 52 |
does, read the help and/or turn it off (it will give a recommended |
| 53 |
setting in the Help). Once you've got your config, use that to build |
| 54 |
the kernels for the rest fo your systems. |
| 55 |
|
| 56 |
I know it's a lot of work, but once you've done it, subsequent |
| 57 |
configs/compiles for kernel upgrades, security patches, etc. will go |
| 58 |
MUCH faster. 1) Because you'll have a pre-defined kernel config. 2) |
| 59 |
You'll know what most of the kernel options are (at least |
| 60 |
superficially) and which ones you need enabled. You'll just have to |
| 61 |
read the help for any new ones that pop up. ;-) |
