Gentoo使用grub2

由于某些原因,grub2没有加入Gentoo portage稳定源中

但这并不能阻止我们使用,使用方法如下:

一. 自己编译grub2

1.从 grub官网 下载 源码 (目前是grub-1.99), ftp站点

2. 编译安装

# tar -zxvf grub-1.99.tar.gz
# cd grub-1.99
# ./configure
# make
# make install
# grub-mkconfig  # 自己编译的没有 update-grub 命令

二. 用 Gentoo 的 emerge 命令安装(参考:http://en.gentoo-wiki.com/wiki/Grub2)

1.运行以下命令:

echo "sys-boot/grub:2" >> /etc/portage/package.accept_keywords 
echo "sys-boot/grub:2" >> /etc/portage/package.unmask 
emerge -av sys-boot/grub:2 

2.得到如下提示:

nehc ~ # emerge -av sys-boot/grub:2 

These are the packages that would be merged, in order:

The following keyword changes are necessary to proceed: 
#required by sys-boot/grub-9999[truetype], required by sys-boot/grub:2 (argument) 
>=media-fonts/unifont-5.1.20080914 ~amd64 
#required by sys-boot/grub-9999, required by sys-boot/grub:2 (argument) 
>=sys-boot/os-prober-1.47 ~amd64 
#required by sys-boot/grub:2 (argument) 
>=sys-boot/grub-9999 ** 

NOTE: This --autounmask behavior can be disabled by setting 
      EMERGE_DEFAULT_OPTS="--autounmask=n" in make.conf. 

Use --autounmask-write to write changes to config files (honoring CONFIG_PROTECT). 

3.解决依赖(注意上一条命令的提示)

# emerge --autounmask-write sys-boot/grub:2

# etc-update
.....                   # 此处选择-3用新配置文件替换掉旧的


4.安装

# emerge sys-boot/grub:2

如下图:

5.安装、配置

# grub2-mkconfig -o /boot/grub2/grub.cfg  #生成配置文件 grub.cfg


# grub2-install --no-floppy /dev/sda      #安装到MBR


6. 大功告成,可以reboot体验了
