Gentoo Installation Checklist

Gentoo Installation Checklist

Create three partitions. 128MB for /boot, 32GB which same memory size for swap and the rest for /

# cfdisk /dev/sda

Format the three paritions:

# mkfs.ext2 /dev/sda1

# mkfs.ext4 /dev/sda3

# mkswap /dev/sda2 && swapon /dev/sda2

Mount Partitions.

# mkdir -pr /mnt/gentoo

# mount /dev/sda3 /mnt/gentoo

# mkdir /mnt/gentoo/boot

# mount /dev/sda1 /mnt/gentoo/boot

Get Stage3 image.

Find nearest mirror from http://www.gentoo.org/main/en/mirrors2.xml

# cd /mnt/gentoo

# wget http://distfiles.gentoo.org/releases/amd64/autobuilds/current-stage3-amd64/stage3-amd64-20140410.tar.bz2

# tar xjpf stage3*

Chroot

# cd /mnt/gentoo

# mount -t proc none proc

# mount --rbind /sys sys

# mount --rbind /dev dev

# cp /etc/resolv.conf etc

# chroot . /bin/bash

# source /etc/profile

Portage

# mkdir /usr/portage

# emerge-webrsync

User accounts

# passwd

# user add -g users -G wheel,portage,audio,void,usb,cdrom -m ${USER_NAME}

# passwd ${USER_NAME}

Configure System

Configure /etc/fstab to match the actual partitioning performed in the step above:

# /etc/fstab

/dev/sda1    /boot    ext2    noauto,noatime    1 2

/dev/sda3    /          ext4    noatime              0 1

/dev/sda2    none     swap   sw                     0 0

Set perferred Portage options

# /etc/portage/make.conf

CFLAGS="-march=native -O2 -pipe"

CXXFLAGS="${CFLAGS}"

# Do NOT change CHOST setting

CHOST="x86_64-pc-linux-gnu"

# Choose desired USE flags

USE="alsa usb"

PORTDIR="/usr/portage"

DISTDIR="${PORTDIR}/distfiles"

PKGDIR="${PORTDIR}/packages"

Timezone

Set the appropriate timezone

# ln -sf /usr/share/zoneinfo/Asia/Seoul /etc/localtime

Kernel

If sys-kernel/gentoo-sources has been selected

# emerge -av sys-kernel/gentoo-sources sys-kernel/linux-firmware

# cd /usr/src/linux

If things are working nicely in the current install environment, it's possibl to use localyesconfig to select all modules currently loaded by the LivcCD.

# make menuconfig

# make -j2

# make modules_install

# make install

Bootloader

Specify the correct setting for the system's firmware. BIOS/MBR is pc, 64-bit UEFI is efi-64, 32-bit UEFI is efi-32.

# /etc/portage/make.conf : PC BIOS settings for GRUB2

GRUB_PLATFORMS="pc"

A simple GRUB2 configuration file for openrc, please see Install systemd guide if you want to install based on systemd.

# /boot/grub/grub.cfg : Example for openrc.

set default=0

set timeout=1

menuentry "Gentoo" {

linux (hd0,1)/vmlinuz-3.14.4-gentoo root=/dev/sda3 rootfstype=ext4 net.ifnames=0 quiet ro

}

Install grub

# emerge --ask sys-boot/grub

# grub-mkconfig -o /boot/grub/grub.cfg

# grub-install /dev/sda

Install Network tools

# emerge --ask sys-apps/iproute2 net-misc/dhcpcd

Clean up

# exit 

# cd /mnt

# umount -R gentoo

# reboot
