有人对make.conf和src.conf感兴趣吗？
本帖最后由 fender0107401 于 2011-04-11 10:51 编辑make.conf一直就有，
src.conf是7.0才引入的东西，
我很想了解应该如何写好这两个文件，想找点资料，谁能指点一下，现在只能自己看着man来弄，
尤其是make.conf重关于buildworld那个部分不明白为什么有那么多关于sendmail的选项，
我能通过这两个文件影响userland到什么程度呢？能以哪些方式去影响呢？

补充：
关于/etc/make.conf的详细情况我已经写到了freebsdchina的wiki上面去了，

[ 本帖最后由 fender0107401 于 2009-5-21 23:49 编辑 ] src.conf 放在那里？ 楼主不说还不知道有src.conf这玩意

src.conf 放在那里？
默认是没有的，要自己创建放到/etc/下面！！ The only purpose of src.conf is to control the compilation of the FreeBSD
source code, which is usually located in /usr/src.As a rule, the system
administrator creates src.conf when the values of certain control vari-
ables need to be changed from their defaults.
看来只是用来影响基本系统编译的，不知道是否影响kernel，应该不影响ports。
The values of variables are ignored regardless of their setting; even if
they would be set to ``FALSE'' or ``NO''. Just the existence of an
option will cause it to be honoured by make(1).
必须明确写出来才能生效。 刚看到了一牛人的make.conf，发现在里面有很多........................不会说，自己看吧

应该会影响到kernel！！
当您编译的时候，很多的功能都会作为模块放到系统中，当您使用src.conf的时候，里面的参数就触使make不去编译该部分，
最后该部分连以模块的方式存在都不行 WITHOUT_BZIP2
Set to not build contributed bzip2 software as a part of the base
system.The option has no effect yet. When set, it also enforces
the following options:
WITHOUT_BZIP2_SUPPORT
WITHOUT_BZIP2_SUPPORT
Set to build some programs without optional bzip2 support.
WITHOUT_CALENDAR
Set to not build calendar(1).
很有意思。 原帖由 gtuiw 于 2008-8-19 17:02 发表 http://bbs.chinaunix.net/images/common/back.gif

的确是影响kernel的，我看到后面的选项里面有明确的说道kernel的，不过我编译内核时习惯不编译模块，^_^
你上面发的那个make.conf是有点复杂，我看了一会，感觉就是把一些编译时候的选项加到里面去了，
编译选项是依靠判断当前编译位置来判断的，
ports的位置不是固定不变的，有的时候会改变，似乎后面的内容实际用处不大吧，
那些关于ports的选项就是在make时制定的那些选项，如果这个ports存在就应用这些选项，
