I can't give away all of everything with this - so you will have to either know what you are doing, or ask questions.

USE AT YOUR OWN RISK!! I will not be responsible if you lose all of your data because you didn't backup anything you might need first!!

"skimpydog-gentoo" is a custom build of Gentoo Linux (as are all customizable), and you may have a copy of it as well.

The installation is as easy as:

0: Boot to Gentoo Live CD (or what ever linux distro - even a live Linux system; you will need to be at a terminal prompt:
;~># _

1: Create your partitions ("swap", "/boot", "/"
See what partitions are currently created:
Example Output:
# fdisk -l

-- Once you make changes in fdisk, they are not applied until you write the changes. If you intend to run multiple operating systems, DO NOT DELETE WHAT YOU NEED!!
**For example do not delete your c:\ drive if you intend to continue to run Windows as well.**
-- If this is an empty hard drive, or if the data on your hard drive is disposable, then you may make any necessary changes and do not have to worry about data loss.
--- I advise to have no less than 40GB setup for your "/" partition assuming you do not have multiple partitions for "/var", "/usr", "/usr/local", "/tmp" etc... If you utilize multiple partitions, be sure to allocate enough space for the partitions so you do not run out of space and have to resize the partitions.
-- If you require to resize your hard disk, I advise to use GParted. GParted may be obtained to put on CD, or USB flash drive. Simply boot to GParted instead of the Gentoo LiveCD for example, and resize the partitions. Then you may boot back to the LiveCD (which may offer more tools) and proceed with the installation once you have dedicated disk space for the install.

Partition sizes (these may be changed as long as they are not too small):
1GB - "/boot"
2GB - "swap space" (Virtual RAM which is much slower than RAM)
40GB - "/"

Be sure to enable swap:
# mkswap /dev/hda2

Turn on Swap:
# swapon /dev/hda2


Mount the partitions:
# mkdir /mnt/gentoo
# mount /dev/hda3 /mnt/gentoo
# mkdir /mnt/gentoo/boot
# mount /dev/hda1 /mnt/gentoo/boot
# cd /mnt/gentoo


2: Download the image (Located in the downloads, you can "wget" it if you know the url [You have to login first to view the downloads]). There are several large files that need to be downloaded (the last one is smaller).
# wget http://thelocation1 http://thelocation2 http://thelocation3

Verify the MD5 checksum is correct against the downloaded files (the hash is on the download page for the file):
# md5sum Gentoo-BackUp.10.11.2010.tar.bz2.*

Then merge these into one large file:
# cat Gentoo-BackUp.10.11.2010.tar.bz2.* > Gentoo-BackUp.10.11.2010.tar.bz2

Verify the MD5 checksum is correct against the final output file (the hash is on the download page for the file):
# md5sum Gentoo-BackUp.10.11.2010.tar.bz2


3: Extract image to the new "/"
# pwd
/mnt/gentoo
# ls
boot Gentoo-BackUp.10.11.2010.tar.bz2 lost+found
# tar xvpfj Gentoo-BackUp.10.11.2010.tar.bz2 -C ./


4: Install Grub
While you are booted to to gentoo Live CD::
# mount /dev/sda3 /mnt/gentoo
# mount /dev/sda1 /mnt/gentoo/boot
# mount -t proc none /mnt/gentoo/proc
# mount -o bind /dev /mnt/gentoo/dev
# chroot /mnt/gentoo
# env-update
# source /etc/profile

# grub
> find /boot/grub/stage1
> root (hdX,X)
> setup (hd0)
> quit

Example for editing /boot/grub/grub.conf
# vi /boot/grub/grub.conf
...
timeout 30
default 2

5: Edit /etc/fstab
# vi /etc/fstab

#/dev/fd0               /mnt/floppy     auto            noauto          0 0
#/dev/hda7              /mnt/BackUp     ntfs            auto,uid=1000,gid=1000  1 2


6: Set your hostname:
# hostname HostName-YouWant
# vi /etc/conf.d/hostname


7: Setup Networking:
# vi /etc/conf.d/net.eth{1,2,3...}
# cd /etc/init.d/ ; ln -s net.lo net.{1,2,3}


8: Setup Video
-- This part can be tricky if you are not familiar with xorg, and related drivers & config files.
There are basically 2 parts to this, or more required to get your Video Hardware Acceleration working (even if you are just running the x11 drivers, not the proprietary drivers)
First, look at the available options (what's currently built in):
# eselect opengl list
You should see your options labeled:
[0] xorg-x11 *
[1] Nvidia
[2] mesa-cvs
[3] ati

If you don't see what you need listed, whereas you are running a totally different video card, or would like to use proprietary drivers (such as for a dual head card to keep hardware acceleration across both screens), then you will need to build these in, and edit the config files for xorg appropriately.

Then to set the opengl option:
# eselect opengl set 0

The Last thing that will need to be done is to make sure your /etc/X11/xorg.conf is configured properly for your Graphics Options as well.
- With skimpydog-gentoo I have built up a couple xorg.conf.*'s (located at /etc/X11/) as examples for using Intel, and nVidia cards with single and Dual Head.

Boot!!
reboot
Eject the CD when propmted

*If you receive errors upon boot, I will advise to review all of your settings based upon where it's messing up. It is possible your LiveCD reads your HardDisk as "hda", and the booted system reads your HardDisk as "sda"; you may be required to boot back to the LiveCD and modify these changes until you figure out what your computer requires - and if a kernel rebuild will be necessary, such as if your SCSI drivers are not built into the kernel.
You may be required to edit "/etc/fstab", and "/boot/grub/grub.conf" to meet your systems requirements if the system does not boot. These options are limitless, so pay close attention to detail.

This is full blown with compiz, MythTV, and other bells and whistles. Great for a laptop as there are many wifi tools already built in (as this was originally built on my notebook).

8: Change root password!!!
When you first login, use the username and password of root/p4ssw0rd!, you can change this once booted into the OS with:
# passwd root


9: Change MySQL password
# mysqladmin -u root -p'p4ssw0rd!' password NEWPASSWORD


10: Create regular User
To create a user, once booted or chrooted, run the script:
# sh /root/add_user.sh

-- this is a simple bash, and perl script that will grab the contents of "/etc/skel" while it creates the user. When you login with this user under X, it will default boot into gnome.
-- Using the add_user.sh script will also create the user to be nested in the required groups to be able to access resources

11: Configure your Sound card
As root, you will need to run ldconfig
$ su
Password:
# alsaconf

-- If you are told that user is not a part of the suoders list, then you will need to add the user to the list of suoders in /etc/group:
# vi /etc/group
append to the line:
wheel:x:10:root,USERNAME,USERNAME2

-- You will need to log-out and log-in for the changes to take effect.
exit



Since this has framebuffer support built in, you may want to reference the "/root/howto_rebuild_kernel-2.6.30-gentoo-r8" as reference, as well as using the .config with the kernel, by utilizing --oldconfig so you can keep relatively the same build making changes as necessary.

The default kernel is built for a P4, and is easily changed for other architectures as well.

I have the packages built around an Intel based ChipSet, with Intel Video utilizing the XFree86 drivers.

As there are no two systems that operate the same (unless you have several of the same chassis models, and you are copying this between them once you have one of them operating properly), there is a great chance you will need to tweak the configurations in every regard. This is not difficult as much as you may be required to boot to a LiveCD to make changes to the newly created environment in order to have a bootable system.

INSTALLER:

So this is an installer I have been working on, and I'm sure I can add more, and prolly fix a few bugs as I'm sure they exist as the more times I install this, I see more functionality that can be added, so please bear with me and I'll add functionality as time goes.

It's a simple bash script that can be run from a USB drive, or built onto a CD.

Create the script:
vi /home/skimpydog-gentoo-installer.sh

It should contain the following, and it may be modified to fit your needs:
#!/bin/bash
# Written by skimpydog

Assuming you are using skimpydog-gentoo, or not but you are using gentoo, and you replace your NIC, or copy your existing OS to another computer, and you notice the NIC now has the name of "eth1", or "eth2" or even a higher number; but you want your NIC to be "eth0" as it is the only NIC.

As stated after compiling udev:

 * If after the udev update removable devices or CD/DVD drives
 * stop working, try re-emerging HAL before filling a bug report
 * 
 * persistent-net does assigning fixed names to network devices.
 * If you have problems with the persistent-net rules,
 * just delete the rules file
 * 	rm /etc/udev/rules.d/70-persistent-net.rules
 * and then reboot.
 * 
 * This may however number your devices in a different way than they are now.


so; rm /etc/udev/rules.d/70-persistent-net.rules

So you know, you start screwing around with a few things, and forget to do a revdep-rebuild every so often after making a lot-o-changes...

Gentoo username # revdep-rebuild 
 * Configuring search environment for revdep-rebuild

 * Checking reverse dependencies
 * Packages containing binaries and libraries broken by a package update
 * will be emerged.

 * Collecting system binaries and libraries
 * Found existing 1_files.rr
 * Collecting complete LD_LIBRARY_PATH
 * Found existing 2_ldpath.rr.
 * Checking dynamic linking consistency
[ 100% ]                 

 * Dynamic linking on your system is consistent... All done.


This may be problematic, and if it is, work with what you can. If you are new to working with Gentoo, or linux for that, if this cannot rebuild with out errors; inotherwords you cannot complete the revdep-rebuild (once packages are re-emerged), you may want to look into sanitizing your "/etc/portage/package.*", for example:

You can have a pretty hefty /etc/make.conf (I had to break the txt formatting for this, so do beware):
