Install Gentoo Stage3 in Thinkpad T40p

This article is an old post I wrote 2 years ago so that I translate it into English Version and MODIFIED some points. The original can be found Here.

Prepare

Press Power button of you computer, insert a linux livecd into the cdrom, then choose to boot from cdrom. When you login into the operating system of the livecd, switch into a terminal and let's start your gentoo installation from here...

Download Gentoo LiveCD or stage3 packs

You can use links or lynx download livecd and stage3 packages from http://gentoo.osuosl.org/releases/x86/, or ftp://ftp3.tsinghua.edu.cn/mirror/gentoo if you stay at cernet.

Partition

Now, we partition the disks and be careful. Here is an example of my computer, and linux can be installed in any primary or extend partitions. You can use fdisk to complete your task. I suggest 4 partitions for your linux system:

• /boot, ext2 format, 50M bytes, where to put vmImage and grub
• /swap, swap format, about size of your physical memory large if you need supsend2(hibernate into disk). You can also totally disable this swap partition if your memory is large enough, such as 1G or 2G bytes :)
• /, root partition can be formated as reiserfs4 due to the performances, 8~10G bytes
• /home, formated as ext3 because ext3 expressed steady and tough.

Here is the output of fdisk run at my disks. Recording your blocks of every partitions is helpful if your lost your mbr unfortunately.

Disk /dev/hda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/hda10           7685        9729    16426431   83  Linux

Mount your partition

Enable DMA feature of your disk, this step is optional.

# hdparm -c 1 -d 1 /dev/hda

Format your partition and mount them, be careful.

# mke2fs /dev/hda7
# mkswap /dev/hda8
# swapon /dev/hda8
# mkfs.reiser4 /dev/hda9
# mke2fs -j /dev/hda10
   
# mount /dev/hda9 /mnt/gentoo
# mkdir /mnt/gentoo/boot
# mount /dev/hda7 /mnt/gentoo/boot
# mkdir /mnt/gentoo/home
# mount /dev/hda10 /mnt/gentoo/home
# mkdir /mnt/gentoo/proc
# mount -t proc none /mnt/gentoo/proc
# mkdir /mnt/gentoo/dev
# mount -o bind /dev /mnt/gentoo/dev

Backup your mbr

• Backup your mbr table:

  # dd if=/dev/(your_disk) of=mbr.save count=1 bs=512
  # sfdisk -d /dev/(your_disk) > partitions.save

  The first of those saves the mbr and the second will store all partition info (including logical partitions, which aren't part of the mbr).
• Restore your mbr table:

  # dd if=mbr.save of=/dev/(your_disk)
  # sfdisk /dev/(your_disk) < partitions.save

Installation

Uncompress

Uncompress your stage3 packages downloaded before. Argument "p" of "tar" makes sure keeping the permit bits of the files in the tarball.

# cd /mnt/gentoo
# tar xvjpf /mnt/cdrom/stages/stage3-xxx.tar.bz2

Install "portage"

This step is optional, and you can use "emerge --sync" to replace when you login into the new system. Download portage, and umcompress into /mnt/gentoo.

# tar xvjf /mnt/gentoo/portage-.tar.bz2 -C /mnt/gentoo/

Configure "make.conf"

Some variables related with the system are configured at /etc/make.conf. The important is that you'd better make sure "USE" variable containing "cjk nls ntpl ntplonly", if the architecture of your computer is x86. It is recommonded to set "ACCEPT_KEYWORDS" as "x86" if you donot wanna test and debug for unstable systems :P

Prepare to Installation

Chrooting

Firstly, copy resolv.conf into the new system:

cp /etc/resolv.conf /mnt/gentoo/etc/

Then, chroot into the new system, begin to install...

# chroot /mnt/gentoo /bin/bash
# env-update && source /etc/profile

Update-to-date portage

Run command:

# emerge --sync

Locale Setting

According to the i18n file "/usr/share/i18n/SUPPORTED", Modifiy /etc/locale.gen. If you use chinese language, here is an example:

en_US.UTF-8 UTF-8
en_US ISO-8859-1
zh_CN GB2312
zh_CN.GBK GBK
zh_CN.UTF-8 UTF-8
zh_CN.GB18030 GB18030

Time Zone Setting

If you stay at timezone +8, then:

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

Modify "/etc/conf.d/clock", and modify it as:

CLOCK="local"

Adjust system time correctly.

# date MMDDhhmmYYYY
# hwclock --systohc

Install Linux Kernel

Download Kernel Source

Firstly, download the lasted stable kernel source:

# USE="-doc" emerge gentoo-sources

Compile Kernel and Install

You can use custom and optimize the kernel options according to the computer hardware.

# cd /usr/src/linux
# make menuconfig
# make && make modules_install
# cp arch/i386/boot/bzImage /boot/linux-

Install GRUB

You can choose to install bootloader into the mbr or /boot by running command "setup (hd0)" or "setup (hd0,6)". Here is the sample run at my computer:

# emerge grub
# grub
grub> root (hd0,6) 
grub> setup (hd0)
grub> quit

Then, Configure your grub profile /boot/grub/menu.lst:

default saved
color light-gray/blue black/light-gray
timeout 2
hiddenmenu

title=Gentoo GNU/Linux
root (hd0,6)
kernel /linux-2.6.17-r8 root=/dev/hda9 ro
savedefault

title=Gentoo GNU/Linux (suspend2)
root(hd0,6)
kernel /linux-2.6.18-suspend2-r1 root=/dev/hda9 ro resume2=swap:/dev/hda8
savedefault

title=Microsoft Windows 2003 Server
rootnoverify (hd0,1)
makeactive
chainloader +1
savedefault

title=Mac OS X
root (hd0,0)
makeactive
chainloader +1
savedefault
boot

Other Steps

setup fstab

Edit /etc/fstab to mount each partition correctly:

/dev/hda7  /boot  ext2  defaults   1 2
/dev/hda8  none            swap            sw              0 0
/dev/hda9  /  reiserfs defaults   0 1
/dev/hda10  /home  ext3  defaults   0 0
none        /proc     proc    defaults          0 0
none        /dev/shm  tmpfs   defaults          0 0
/dev/hda6 /home/wine vfat defaults,shortname=mixed,utf8,fmask=133,dmask=022,uid=shokn,gid=users 0 0
/dev/hdc /mnt/cdrom iso9660 ro,noauto,user,utf8 0 0

Add a new user

Add a new user named "shokn":

# useradd shokn-m -G users,wheel,portage,audio,games -s /bin/bash
# passwd shokn

Active the ethnet card

Add net.eth0 into the runlevel boot

# rc-update add net.eth0 boot

If you have a static IP address rather than a DHCP address, then modify /etc/conf.d/net:

config_eth0=("192.168.0.13 netmask 255.255.255.0")
routes_eth0=("default via 192.168.0.3")

Here is another useful script to setup your eth0 address from gentoo livecd-tools:

Now, You have nearly completed this installation. (to be cont.)
