Instalacion base de Gentoo:

Arrancar el sistema desde el LiveCD.

Configurar la interfaz de red:

# net-setup eth0

Para seguir la instalacion de manera remota:

Cambiar contraseña de el usaurio root:

# passwd root

Iniciar el servicio sshd para manejo remoto:

# /etc/init.d/sshd start

Crear las particiones iniciales:

# cfdisk /dev/sda


Name	Flags		Part Type	FS Type		[Label]		Size (MB)
-------------------------------------------------------------------------------------
sda1	Boot		Primary		Linux ext2			98.71
sda2			Primary		Linux				509.97
sda3			Primary		Linux ext3			1998.75
sda4			Primary		Linux LVM			248387.01

Crear sistemas de archivos:

# mke2fs /dev/sda1
# mke2fs -j /dev/sda3

Configurar y activar particion swap:

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

Montar particiones bases:

# mount /dev/sda3 /mnt/gentoo
# mkdir /mnt/gentoo/boot
# mount -t ext2 /dev/sda1 /mnt/gentoo/boot

Configuracion LVM:

# modprobe dm-mod

(Avoid scanning your cdrom)
# mkdir -p /etc/lvm
# echo 'devices { filter=["r/cdrom/"] }' >/etc/lvm/lvm.conf
# vgscan
  Reading all physical volumes.  This may take a while...
  No volume groups found
(Make any previously set up volume groups available)
# vgchange -a y
  No volume groups found
# pvcreate /dev/sda4
  Physical volume "/dev/sda4" successfully created

# vgcreate system /dev/sda4
  /etc/lvm/backup: fsync failed: Invalid argument
  Volume group "system" successfully created

# lvcreate -L10G -nusr  system
  Logical volume "usr" created (Further similar messages not displayed)
# lvcreate -L5G  -nhome system
# lvcreate -L5G  -nopt  system
# lvcreate -L10G -nvar  system
# lvcreate -L2G  -ntmp  system
(As an example, let's extend a logical volume with 5 extra Gbytes)
# lvextend -L+5G /dev/system/home

# mke2fs -j /dev/system/usr
# mke2fs -j /dev/system/home
# mke2fs -j /dev/system/opt
# mke2fs -j /dev/system/var
# mke2fs -j /dev/system/tmp


(Make sure you have mounted your root partition as described in the handbook first)
# mkdir /mnt/gentoo/usr
# mount /dev/system/usr /mnt/gentoo/usr
# mkdir /mnt/gentoo/home
# mount /dev/system/home /mnt/gentoo/home
# mkdir /mnt/gentoo/opt

Configuracion de LVM2 en Kernel:

[*] Multiple devices driver support (RAID and LVM)
< >   RAID support
<*>   Device mapper support

SI se puso como <M> entonces agregarlo para que cargue al inicio del sistema:

dm-mod

# emerge lvm2
(At the time of writing, the stable version is 2.00.08.
With version 2.00.08, prevent lvm2 from probing your cdrom by doing:

# echo 'devices { filter=["r/cdrom/"] }' >> /etc/lvm/lvm.conf

(Versions 2.00.15 and later come with a /etc/lvm/lvm.conf
Edit your /etc/lvm/lvm.conf and follow the comments

# nano -w /etc/lvm/lvm.conf
