Installing Linux System

Check each partitions, in order, and make sure that it matches what you intended to enter. When you’re satisfied, use the Tab key to select the OK button and then press Enter.

The Save Changes dialog box appears.

If you’re satisfied with the partitions that you have created. Select Yes.

Until you select the Yes button, you have not actually written any partitions to disk. You do have the option to select the No Button, which takes you to Step 9. If you Select Cancel, you return  to the Desk Druid dialog box with all of your partitions still in place.

If you have an older system with less than 32MB of memory, then you see the Low Memory dialog box. This dialog box tells you that the Red Hat installation process will format and activate the swap partition immediately. Select Yes to continue.

In the Choose Partitions to Format dialog box, choose either to format or not to format each of your partitions.

The default is to format. If this is your first time installation or you want to start with a completely fresh one, then tab down to the Ok button and press Enter.

If you’re are installing Linux and you want to save the information stored on such partitions such as/home or /usr/local, then Tab down to those menu items and press the Space bar to deselect the asterisks. From there tab to Ok and press Enter.

Introducing the Linux file system tree

The Linux file system is like a tree turned upside down, as shown in the following figure. The top of the upside-down tree is represented by a /(slash) and is called the root. A series of limbs, branches, and leaves are below the root. The limbs are called mount points, the smaller branches are your directories and the leaves are your files.  Each mount points is a disk partition, and the disk partition is mounted on the directory of the limb above it. When the disk partition  is mounted on the directory branch, it turns that branch into another limb, allowing for even more branches to be positioned and attached below the mount point.

Normally, you need at least a root partition in your directory structure( the upside-down tree) and a swap space ( particularly if you have a system with under 16mb of RAM). Therefore, at a minimum, you should set up two types of disk space: a Linux file system starting at the root and a swap space. Theoretically; you don’t have to set up swap space, and some people choose not to. If you do, however you can run more programs than you have real memory you have on your system.

As mentioned, at a minimum, setting up a separation partition for your user files( usually called the home directory) is better and setting up multiple disks partitions  for your Linux files is even better still. This setup makes backing up your files and updating your system to new versions of Linux much easier. The downside is that you have to leave empty space in each partition for new files, and these empty spaces add up. A reasonable analogy is using a filling cabinet to store your personal files versus a single box.

Data Movement in Linux – Often No More than Renaming

Strictly speaking the file still has not moved.  The data bits are still on the same part of the disk where they were in the first place originally.  The file specification ( the-directory-path plus the filename) that you use to talk about the file is different so that it appears to have moved , whereas it has not in actuality.

In early versions of Unix , the users were not allowed to use mv to move a file from one disk partition to another , you could only copy it ny using the  cp(1) command.  Linux allows you to use the mv command to move a file anyplace.  Normally , mv leaves the data in place and just changes the file name or the directory where the name is placed.  But when the file is moved across the disk partitions ( for example form /usr to /home in a lot of Linux systems) , the data is copied to the new disk partition, the new name is put in place.  In that partition’s directory structure, and the name and file data are removed from the old disk partition.

United Linux Specs as well as Coordination Blueprints

On top of this the United Linux participants were to include supplementary media which would of provided easy opportunities which would allow easy configuration and even branding of the distributions look feel install applications and value added services.  The obvious point in this was – apart from the branding is that each of partners could produce task or region or regions specific offerings that still adhered to the United Linux overall specifications and specs .

Colloborative Linux Distro

These individual distros and their partners hoped that other distros of Linux would be marked under their respective brands, but would be powered by a consistent United Linux which mean that the user could be confident that the user would be published with a United Linux and thus a measure of consistency and user functionally would easily exist across a customer and user base – for the first time in the Linux unix user base and communities.

Thus the UI ( United Linux) brand would thus of reduced the amount of mainstream Linux distros to the well managed group of five (5) – that at the time being Red Hat, Mandrake , United ,Debian and Slackware. The bets were on that time that in the enterprise sector tht Re Hat and United Linux would come to dominate. Well at the time those were the predictions of the Linux market share dominant distros.

Linux History – June 2002 – 4 Major Vendors Join Forces

In June 2002 four of the largest Linux distribution vendors joined forces to break down what they had identified as the main barriers to the widespread adoption of Linux in an enterprise- Caldera , SuSE, Conectiva and TurboLinux announced that they would collaborate on a common Linux fore to create the next generation of a Linux Distribution ( distro) to make deploying and supporting software easier and resolve the common problem of binary incompatibility between Linux distributions.

Desktop Linux Users Numbers Continue to Grow

desktop linux users doubled

Some great news from desktop linux.com! They recently revealed the desktop survey results. The facts are there, the number of desktop linux users has doubled the last year!

And what is the desktop linux users distribution of choice? The Ubuntu family (Xubuntu, Kubuntu, Ubuntu, Ubuntu Studio, Edubuntu) leads on, and SuSe is the second runner up.

The survey shows us that more and more people are trying out a GNU/Linux distro, more and more people are getting aware that they can choose their OS. Up until Dell started to cooperate with Ubuntu, we had to accept that a PC you ordered came with a MS OS install (unless you bought parts and built your own pc).
