1. Determine disk name # lsblk

2. Launch parted # parted -a optimal /dev/sda

3. Erase everything mklabel gpt

4. Make partitions

unit mib
mkpart primary 1 129
name 1 boot
mkpart primary 129 4225
name 2 swap
mkpart primary 4225 -1
name 3 rootfs
set 1 boot on
print

5. Create filesystems

# mkfs.fat -F 32 /dev/sda1
# mkfs.ext4 /dev/sda3
# mkswap /dev/sda2
# swapon /dev/sda2

6. Mount root partition

# mkdir -p /mnt/gentoo
# mount /dev/sda3 /mnt/gentoo
# cd /mnt/gentoo

1. Check that date is correct. See here if it's wrong. # date

2. Download tarball a. Find download link from: https://www.gentoo.org/downloads b. # wget <url>

3. Validate tarball

# wget <url>.DIGESTS
# openssl dgst -r -sha512 stage3-.tar.xz

Ensure a pair of the numbers above match

4. Unpack # tar xpf stage3-.tar.xz --xattrs-include='*.*' --numeric-owner

5. Configure options # nano -w /mnt/gentoo/etc/portage/make.conf

For XPS 8500, add the following:

CHOST="x86_64-pc-linux-gnu"
CFLAGS="-march=native" 
CFLAGS="${CFLAGS} -O2 -pipe"
CXXFLAGS="${CFLAGS}"

MAKEOPTS="-j8"

INPUT_DEVICES="evdev"
VIDEO_CARDS="nvidia"

USE="X bluetooth dbus pulseaudio savedconfig xinerama zsh-completion"

PYTHON_TARGETS="python2_7 python3_6"
PYTHON_SINGLE_TARGET="python3_6"

GRUB_PLATFORMS="efi-64"

1. Add mirrors # mirrorselect -i -o >> /mnt/gentoo/etc/portage/make.conf

or, if mirrorselect isn't available, add this to the bottom of /etc/portage/make.conf: GENTOO_MIRRORS="http://lug.mtu.edu/gentoo/ http://mirrors.evowise.com/gentoo/"

2. Repo config

# mkdir -p /mnt/gentoo/etc/portage/repos.conf
# cp /mnt/gentoo/usr/share/portage/config/repos.conf /mnt/gentoo/etc/portage/repos.conf/gentoo.conf

3. Copy DNS info # cp --dereference /etc/resolv.conf /mnt/gentoo/etc/

4 Mount filesystems

# mount --types proc /proc /mnt/gentoo/proc/
# mount --rbind /sys /mnt/gentoo/sys/
# mount --rbind /dev /mnt/gentoo/dev/

# test -L /dev/shm/ && rm /dev/shm/ && mkdir /dev/shm/
# mount --types tmpfs --options nosuid,nodev,noexec shm /dev/shm
# chmod 1777 /dev/shm/

5. Enter the new environment

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

6. Mount boot # mount /dev/sda1 /boot/

7. Update the ebuild repo # emerge --sync

8. Select the right profile [16] default/linux/amd64/17.0/desktop (stable)

# eselect profile list
# eselect profile set 16

9. Update the @world set # emerge -auvDN @world

1. Set the timezone #
