我写的kernel.spec,大家看看

aniuge007

里面肯定有错误,不过我已经用标准的kernel打包成功,大家看看.

不知道改写 grub.conf 的脚本包含在里面没有 ？？

aniuge007

[ -x /sbin/new-kernel-pkg ] && /sbin/new-kernel-pkg --mkinitrd --depmod --install 2.4.22
这个就是改写grub.conf的.

gugong

噢，谢谢 ！

aniuge007

国际惯例，自己顶。

aniuge007

这是修改过的，原因是使用了gcc的优化选项，因为公社里有人测试相对于redhat的内核能有7%-10%的性能提高。[code:1]%define KERVER 2.4.22

一天的劳动成果，大家支持一下。

spec里有错，查出有奖。

gugong

枯燥而且没有流程说明、功能解释的程序，是没人会看的。

ajinn

O2真的快吗
