delete existing file system.

mount /dev/sdb9 /mnt/gentoo
rm -rf /mnt/gentoo/*
mkdir home boot
mount /dev/sdb6 /mnt/gentoo/boot
mount /dev/sdb8 /mnt/gentoo/home
rm -rf /mnt/gentoo/boot/*

Optional:format file systems(/boot and / partition, no necessary to format /home partition)

mkfs.ext2 /dev/sdb6
mkfs.ext4 /dev/sdb9
mount /dev/sdb9 /mnt/gentoo/
cd /mnt/gentoo/
mkdir boot home
mount /dev/sdb6 /mnt/gentoo/boot/
mount /dev/sdb8 /mnt/gentoo/home/

stage3

Gentoo:安装Stage3 the sohu mirror seems to be wrong.

cd /mnt/gentoo
wget http://mirrors.163.com/gentoo/releases/amd64/autobuilds/current-stage3-amd64/stage3-amd64-20161229.tar.bz2
sha512sum stage3-amd64-20161229.tar.bz2
cat stage3-amd64-20161229.tar.bz2.DIGESTS

tar xvjpf stage3-*.tar.bz2 --xattrs

then edit /etc/portage/make.conf

CFLAGS="-march=native -O2 -pipe"
MAKEOPTS="-j9"
...
USE="bindist X dbus -gtk -gnome -qt3support -ldap"
CPU_FLAGS_X86="aes avx avx2 fma3 mmx mmxext popcnt sse sse2 sse3 sse4_1 sse4_2 ssse3"
INPUT_DEVICES="evdev"
VIDEO_CARDS="intel nvidia"
...
GENTOO_MIRRORS="http://mirrors.163.com/gentoo/"

then mount system and chroot to new system:

cp -L /etc/resolv.conf /mnt/gentoo/etc/
mount -t proc proc /mnt/gentoo/proc
mount --rbind /sys /mnt/gentoo/sys
mount --make-rslave /mnt/gentoo/sys
mount --rbind /dev /mnt/gentoo/dev
mount --make-rslave /mnt/gentoo/dev

chroot /mnt/gentoo /bin/bash
source /etc/profile
export PS1="(chroot) $PS1"
