 </overlay>简单的几个地方解释一下
代码:type = "git"    <<<---- 这里是指远程仓库的类型,有svn, git, rsync, hg等
               src = "git://gitorious.org/exherbo-cn/oahong-gentoo.git"   <<<--- 这个是源地址很重要,会用git的朋友可能一眼就看明白了,比如在github把那个地址抄下来就是了
               contact = "oahong@gmail.com"   << --- 联系人
               status = "unofficial"                   << ---  非官方仓库 (进官方了就不用自己弄了,嘿嘿)
               name = "oahong-gentoo">          << --- overlay的名字,即是  layman -a  overlay_name 要用到的,如果要空格的话layman -a " abcd efgh " 括起来,不过不建议这么用cat /etc/layman/layman.cfg

代码:[MAIN]

#-----------------------------------------------------------
# Remote overlay lists will be stored here
# layman will append _md5(url).xml to each filename

#-----------------------------------------------------------
# The list of locally installed overlays

#-----------------------------------------------------------
# Strict checking of overlay definitions
#
# Set either to "yes" or "no". If "no" layman will issue
# warnings if an overlay definition is missing either
# description or contact information.
#
nocheck : yes

#-----------------------------------------------------------
# Umask settings
#
# layman should usually work with a umask of 0022. You should
# only change this setting if you are absolutely certain that
# you know what you are doing.
#
#umask : 0022------------------------------------------------------------

layman -f
layman -a oahong-gentoo
cd /usr/local/portage/layman 去ls一下
以后layman -S 就帮忙把它给同步了

代码:在/etc/layman/layman.cfg文件中可以找到以下的备注信息
#overlays : http://www.gentoo.org/proj/en/overlays/layman-global.txt
#            http://dev.gentoo.org/~wrobel/layman/global-overlays.xml
#            http://mydomain.org/my-layman-list.xml
#            file:///usr/portage/local/layman/my-list.xml   <<---- 因为拷到本地来使用,所以就选它了其实xml看了一下英文也没啥好解释的,参考http://www.gentoo.org/proj/en/overla...man-global.txt 抄一个相同类型的照猫画虎就成了
同步到layman的目录中,我一般是不相接加入 make.conf 里,只是建一个本地的overlay,因为会跟现在有一些仓库冲突,然后软链接过来使用
嘿嘿,很简单了吧,以后自己建一个git的仓库就可以用上这招了,让gentoo来得更方便一点吧
PS: 要是能加注彩色就棒了,目前只会 [ code ]
