FreeBSD 9.1内核kernel文件和模块文件

FreeBSD内核kernel文件和模块文件

当指定模块编译的时候，make.conf文件如下：
MODULES_OVERRIDE=xfs
那么，安装的内核就是：
ztz0223@BTazuo:/boot/kernel % ll
total 66996
-r-xr-xr-x  1 root  wheel  16031061 Feb 19 14:36 kernel*
-r-xr-xr-x  1 root  wheel  48269559 Feb 19 14:36 kernel.symbols*
-rw-r--r--  1 root  wheel     18604 Feb 19 14:42 linker.hints
-r-xr-xr-x  1 root  wheel    537273 Feb 19 14:42 xfs.ko*
-r-xr-xr-x  1 root  wheel   3534697 Feb 19 14:42 xfs.ko.symbols*
除了kernel相关的文件，然后就是xfs的ko文件了，xfs是模块，是可以加载的。

那么不指定MODULES_OVERRIDE的时候，就会在编译kernel之后，完全编译和安装所有模块如下：
ztz0223@BTazuo:/boot/kernel.old % ll | less
total 199700

我这里仅仅列出了部分，至于有多少模块可以看/usr/src/sys/modules文件夹的Makefile：
ztz0223@BTazuo:/usr/src/sys/modules % less Makefile

这里也是仅仅列出了部分的需要完整编译的文件夹。
