定制FreeBSD内核

参考书籍:FreeBSD 使用手册,BSD HACKS

首先进入目录

# cd /usr/src/sys/i386/conf

复制一份配置文件命名为HACKER-PIAO
# cp GENERIC HACKER-PIAO

如果说不存在这个目录的话可以进行如下操作:

#sysinstall, 选择 Configure, 然后是 Distributions、 src,选中其中的 base 和 sys。 如果您不喜欢 sysinstall 并且有一张 “官方的” FreeBSD CDROM, 也可以使用下列命令, 从命令行来安装源代码:# mount /cdrom# mkdir -p /usr/src/sys# ln -s /usr/src/sys /sys# cat /cdrom/src/ssys.[a-d]* | tar -xzvf -# cat /cdrom/src/sbase.[a-d]* | tar -xzvf -

接下来定制内核 HACKER-PIAO 主要是参考使用手册和BSD HACKS,这里我列出 read more »
