Alternate install

Expand

This wiki is intended to make deployment of gentoo on alternate live media quick and easy. This is not a substitute of reading the handbook, but a skimmed version of it adapted to xubuntu's live desktop media, with high performance JFS file system, xfce4, network-manager, firefox, irc chat, grub2, porthole package management and pidgin. Just like your live media, preferably dropped in via unetbootin. (note. 'emerge -av -j5 package' will merge 5 jobs at once for a quad core, if you have a dual core, emerge -av -j3, 6core emerge -av -j7) (note. try xubuntu with out installing.) (get your xubuntu desktop iso from here. http://mirror.anl.gov/pub/ubuntu-iso/CDs-Xubuntu/12.04/release/ x86 if working on old hardware amd64 if newer than 2006)

Install

flash plugin

to watch media / etc online while installing gentoo as it takes quite long.

user $sudo apt-get update

user $sudo apt-get install flashplugin-installer

step1

Boot xubuntu live rescue cd or live usb thumb drive.

step2

Attach to any network desired, with internet access to gentoo mirrors, through nm-applet and networkmanager provided by the xubuntu live media.

step3

Expand

Open a terminal (top left mouse icon > accessories > terminal emulator) & run. (root command, as in sudo su your terminal)

root #cfdisk /dev/sda

• make new > primary > 150mb > beginning > bootable flag > /dev/sda1

Note
if you intend on using a swap file skip swap partition creation & just make rest of the drive root

• highlight free space > new > primary > 1000mb > beginning > /dev/sda2 > highlight type and press enter 3 times to enter it as a swap mode partition.
• highlight free space > primary > rest of drive space, just press enter.

• write > yes > press enter > quit

step4

Expand

With partitions squared away format them for instillation. storage

Note
if using a swap file mkfs.jfs /dev/sda1 && mkfs.jfs /dev/sda2

root #mkfs.jfs /dev/sda1 && mkfs.jfs /dev/sda3

Y > enter > Y > enter

swap partition:

root #mkswap /dev/sda2

If mkswap fails, go back to step 3 and cfdisk the drive again. If you recieve messages to reboot do so. If using swap file continue on.

step5

Expand

Mount storage and activate swap partition.

swap partition:

root #

mkdir /mnt/gentoo
mount /dev/sda3 /mnt/gentoo
mkdir /mnt/gentoo/boot
mount /dev/sda1 /mnt/gentoo/boot
swapon /dev/sda2

swap file:

root #

mkdir /mnt/gentoo
mount /dev/sda2 /mnt/gentoo
mkdir /mnt/gentoo/boot
mount /dev/sda1 /mnt/gentoo/boot

to make an 4 gig swap file

root #

dd if=/dev/zero of=/mnt/gentoo/swap bs=1024 count=4194304

root #mkswap /mnt/gentoo/swap

root #chown root:root /mnt/gentoo/swap

root #chmod 0600 /mnt/gentoo/swap

root #swapon /mnt/gentoo/swap

step6

Expand

Get stage3 ready for chrooting.

Launch firefox, and go to http://www.gentoo.org/main/en/mirrors2.xml and select a local mirror.

Go to releases/YOUR COMPUTERS ARCH!/current-stage3, grab stage3-yourarch-datemade.tar.bz2 & stage3-yourarch-datemade.tar.bz2.DIGESTS.

root #

cp /home/xubuntu/Downloads/* /mnt/gentoo
cd /mnt/gentoo

Check stage3 checksum.

root #

head -n 2 stage3*.DIGESTS | sha512sum -c

If it checks OK procede.

root #

tar xvpf stage3*.bz2

step7

Expand

Wrap up chrooting, mounting, and chroot.

root #

mount -t proc none /mnt/gentoo/proc/
mount --rbind /dev /mnt/gentoo/dev/
ntpdate pool.ntp.org

(HERE COMES GENTOO!)

root #

chroot /mnt/gentoo/ /bin/bash

(Your terminal prompt should now be blood red saying xubuntu / #) (Chroot makes your /mnt/gentoo act as system root / step 8 - step 14 require you to be in chroot. You are in and building your gentoo system up at this point.)

step8

Set environment up.

root #

env-update
source /etc/profile

passwordless root install

Expand

or to make a more secure install of gentoo, install sudo later on, and never set a password for root....

• make a user

root #useradd -m -G users user

• add the user to the wheel group (change user to the actual user you added)

root #gpasswd -a user wheel

• set a password for the user

root #passwd user

Note
When you enter your password, the block will not move, this is normal.

to get to root when finished installing

root #sudo su

passworded root install

Expand

Password, set a root password don't be locked out when you restart

root #passwd

Note
When you enter your password, the block will not move, this is normal

DNS client setup

root #echo "nameserver 8.8.8.8" >> /etc/resolv.conf

root #mv /etc/fstab /etc/fstab.example

root #wget -O /etc/fstab https://gist.github.com/666threesixes666/5705917/raw/a04366330da80b9f5ccc9ae15994a696a3072ea7/fstab

if using a swap file edit in /dev/sda2 && out swap. replace swap line with this one.

Note
it takes a long time to sync, 5-10 minutes.

Sync to Merge.

root #emerge-webrsync

Important
rm /usr/portage/metadata/timestamp.x will make it so you can sync again if first sync failed

emerge --sync is the old deprecated insecure way to sync.

root #emerge --sync

step10

Expand

Open another terminal tab. (ctrl + shift + t with terminal in the foreground & highlighted)

again chroot to set some settings while sync is loading up.

user $sudo su

root #chroot /mnt/gentoo/ /bin/bash

set time zone (example is USA DETROIT)

root #cp /usr/share/zoneinfo/America/Detroit /etc/localtime

root #ln -s /proc/self/mounts /etc/mtab

root #rc-update del mtab boot

root #echo "en_US.UTF-8 UTF-8" >> /etc/locale.gen

root #locale-gen

root #eselect locale set en_US.utf8

root #echo "sys-kernel/linux-firmware" >> /etc/portage/package.accept_keywords

root #echo "sys-kernel/vanilla-sources" >> /etc/portage/package.accept_keywords

• If your going to be using nvidia propietary drivers mask latest kernels

root #echo ">sys-kernel/vanilla-sources-3.10.0" >> /etc/portage/package.mask

root #echo "media-libs/mesa xa" >> /etc/portage/package.use

Re-compile the linux kernel. open a new terminal tab & chroot again. (ctrl + shift + t with terminal in the foreground & highlighted)

user $sudo su

root #chroot /mnt/gentoo/ /bin/bash

root #

cd /usr/src/
ln -s linux* linux
cd linux

Post install

Expand

Reboot into your shiny new gentoo.

You will most likely want to make a non privileged user account.

root #useradd -m larry

You will most likely want to add it to groups also.

root #gpasswd -a larry wheel

root #passwd larry

Enter the users new password two times, the block will not move, this is normal behavior.

Mirror selection will help speed up package fetching.

root #mirrorselect -s3 -D -o >> /etc/portage/make.conf

Error Recovery

Expand

If your system fails to boot don't delete just yet. open a terminal and become root

user $sudo su

root #

mkdir /mnt/gentoo
fsck.jfs /dev/sda1
fsck.jfs /dev/sda3
mount /dev/sda3 /mnt/gentoo
mount /dev/sda1 /mnt/gentoo/boot
mount -t proc none /mnt/gentoo/proc
mount --rbind /dev /mnt/gentoo/dev
chroot /mnt/gentoo /bin/bash

emerge & recompile your kernel to more stable settings.

Rebuild kernel take 2

Expand

If kernel failed to compile the first time follow these steps. (in chroot environment/error recovery)

root #make clean && make distclean && make mrproper

root #cp /boot/config-original /usr/src/linux/.config

root #cd /usr/src/linux && make menuconfig

reconfigure to a solvent state

root #make && make modules_install && make install && update-grub2

remove boot media and reboot.

Kernel Protips

Expand

Live media generally use kernel modules.

To see what modules are loaded...

root #lsmod

Dmesg is also your friend, you can find ethernet and wireless modules like this.

root #dmesg | grep eth

root #dmesg | grep wlan

lspci is your friend also

root #lspci -k | grep mod

when in menuconfig / will search for modules and print information about them, including where to navigate to in the menu to activate them, and any other options required to activate them.

Note
do not over customize your kernels. you can build a kernel with blank generic configs, and do not need to import previous configs. previous configs can be tainted, and introduce failure. start from scratch, get a known working config, then start to import / tweak / perfect your .configs.
