Gentoo Linux 软件包镜像使用帮助

gentoo 镜像为 Gentoo Linux 的软件包镜像，包含 distfiles，liveDVD，stage3 等文件，ebuilds 镜像为 gentoo-portage。

使用方式

用你喜欢的编辑器编辑 /etc/portage/make.conf ，找到 GENTOO_MIRRORS 变量，修改为 GENTOO_MIRRORS="https://mirror.bjtu.edu.cn/gentoo/"。

一个完整的 /etc/portage/make.conf 文件样例如下（来自一位不愿意透露姓名的热心 Gentoo 用户张三同志）（由于 Gentoo Linux 存在较高配置灵活性，切勿直接复制此文件！）：

# These settings were set by the catalyst build script that automatically
# built this stage.
# Please consult /usr/share/portage/config/make.conf.example for a more
# detailed example.
CFLAGS="-march=native -O2 -pipe"
#CXXFLAGS="${CFLAGS} -std=c++14"
CXXFLAGS="${CFLAGS}"
# WARNING: Changing your CHOST is not something that should be done lightly.
# Please consult http://www.gentoo.org/doc/en/change-chost.xml before changing.
CHOST="x86_64-pc-linux-gnu"

# These are the USE flags that were used in addition to what is provided by the
# profile used for building.
