 |
|
Does anyone has yet tried to create a kernel flag system similar to the use flag system ?
By this, we could create a more optimised kernel on the gentoo way, but also more secure because the flag make sure we have every time the good option, the right module... ?
I think this is an idea for gentoo dev, but let's talk about what you feel about this idea...

I do not actually understand your point.
Or, If I understand it, is'nt it exactly what we already get ?
What prevents you to see CONFIG_XYZT thingies as "kernel use flags" that you put in a file (.config) that you could see as an equivalent to the USE part of your make.conf ?
The only difference I actually see is that, for "kernel use flags" you get some semi-graphical front-end to modify them.
Being used to making FreeBSD kernels, I personally ... started on gentoo... making my .config... under... vi  |

here, I am not in the mood with graphical front-end to do that...
My idea, is to define a serie of flags (exactly the same idea as use flags) which you can define to automatically build the kernel as you want, as every over ebuild !
For the beginner, I think it allows to build more secure kernel : you have just the option you want, witout those unnecessary, or those dangerous... In plus, you forget nothing !
For exemple, I could make :
| Code: | | KERNEL_FLAGS="lvm bluetooth -raid reiserfs ext4 -wifi tg3" |
Of course, we can use the USEflags to configure the kernel (lvm is the USEflags, reiser too...), and each drivers would be compiled if its name is in the kernel flag. Plus : an "M" added at the end of the flag indicates that we like it as module. Exemple : athk9M means I would like my wifi card driver as module.

This change a little bit each time, and the .config is not a static file ! I think of putting it in a make-kernel.conf, or anywhere else... The config is quite a hard thing to do ! It can help the beginner, but the guru himself has every the right to do in the way he want !
