Comp 3000 2011 Report: Tiny Core Linux

From Soma-notes

Part 1

Background

The name of the distribution that will be discussed is called Tiny Core Linux. The goal of this distribution is the creation of a nomadic ultra-small graphical desktop operating system that is capable of booking from CD-ROM, pen drive, or from a hard drive. Its target audience is mainly for people who want a fast powerful and flexible operating system. Though it can be used without a thorough knowledge of Linux the more the know the more useful it is.Tiny Core is made up of contributors and volunteers its main founder was Robert Shingledecker and with other developers, administrators and graphic designers they were able to come up with what is know know as Tiny Core Linux. Tiny core is available for download on their website. <http://distro.ibiblio.org/tinycorelinux/>.

Installation/Start up

Tiny Core can be downloaded and installed in several ways. Tiny Core can be downloaded as a stand alone program which needs TCB to run and includes a desktop. MicroCore Linux includes a CLI. And last but not least MultiCore which includes TinyCore, MicroCore, networking tools and an installer. so the more advanced user one is the more advanced the download so everyone's need is meet. Tiny Linux can be installed in many ways below will outline some of those ways It can be installed from cloud mode. This loads the distribution from a CD. Any application that a made through this mode will be saved to memory, one downside though is that applications will have to be reloaded with every reboot.

  • To install insert CD and press OK

It can be installed straight to a USB stick making it portable. Just remember to back it up before shut down or all data will be lost.

  • To install in the banner at start up type tinycore waitusb=10 and hit enter. Look for the mnt/ directory and click the plus sign. The USB should be listed at sda1. Click on the drive and create a new directory name it tce/. This will be the default save location for all applications and files . Upon start-up this directory will be found automatically

It can also be installed from a USB stick boot mode but make sure no important documents are on the UBS because it will be deleted upon install

  • To install in the banner type tinycore waitusb=10 and hit enter. Look for the icon that has a screwdriver displayed on it. When prompted click the HD/USB install button.
Startup desktop

Basic Operations

Some basic operations

  • To install an application select the appbrowser icon .Look for the needed applicatrion to install and hot go.
  • To open the editor type editor and a file name if needed.
  • To view minimized programs or to switch between programs right click and select the needed program.
  • The user also has the ability to create a new desktop and this can be done my right clicking the current desktop.
  • The control panel can be accessed from the bottom of the screen from the panel button.
  • top can be accessed by right clicking and selecting the system tools option then selecting the top option instead of going through the terminal
Some applications running

Usage Evaluation

Using Tiny Core takes a little getting to use. however on a scale of 1 to 10 transitioning to using Tiny Core after using a Linux distribution like Ubuntu or even windows is a 5. mainly because the set up a different from what i am usually used to. Everything in Tiny Core Linux is arrange out of the norm this set up if very similar to a mac with the icons at the bottom of the page. The control panel view is a lot different from what I am used to

Part 2

Software Packages

The packaging format used in Tiny Core is through the appbrowser. It has to be connected to the internet before any extensions can be installed. It should be noted that because tiny core is so small it does not come with most standard programs like an internet browser, or a music player but it is easily accessible to be installed through the appbrowser.To access the appbrowser simply right click on the desktop hover over systems tools and the appbrowser option should then be visible. Click the connect button to set up a connection and all available extensions should be visible considering the internet connection is good.Then clicking on an extension will download it and all its dependencies. Deleting an extension is just as uncomplicated as installing one. open app audit, then dependencies, then build reporting database, select the application that you want removes click dependencies then mark for deletion. the computer has to be restarted for the changes to take effect. The most intuitive way to update an extension is through terminal with the key word tce-update. The extension library is extensive for such a little distribution and can be found at this link[[1]. Finding extensions can also be done through terminal using the keyword ab or ab search_term. starting an application takes the command tce-run app_name. and loading a command can be done through tce-load -i app_name

Major Packages

[2]

LIBC

  • Tiny Core uses version 2.13 by Roland McGrath et al. The current version available is version 2.14 so Tiny Core is not too far behind[3]

FREE TYPE

  • Tiny Core uses version 2.4.4. the latest version available is 2.4.8
  • It was probably chosen because free type is made to be small, efficient, and portable and would be very compatible with a small system.[4]

LINUX KERNEL

  • Tiny Core is run kernel version 3.0.3 the latest version is 3.1.1

Module -INIT-TOOLS

  • Tiny core runs version 3.11.1 of module-init-tools the latest version is 3.16
  • it is run on tiny core because it would make sense to have a program to handle inserting, loading and removing kernel modules for Linux [5]

UDEV

  • runs version 173 on Tiny Core the latest version is 174
  • udev provides a dynamic /dev directory and persistent device names. This is useful for Tiny Core because users have the choice of running TC right from a USB stick and a program like this would be useful for that [6]

XORG-SERVER

  • Tiny Core runs version 6.6.1 the latest version is 7.6
  • this package is useful in Tiny Core because it provides the ability to package a release for free open source software.[7]

XZ

  • Tiny Core runs version 5.0.0 and the latest version is 5.0.3
  • this package enables data compression which is needed for tiny core because it is a small distributions that needs to be able to do a lot.[8]

Initialization

Tiny Core has many loaders in common with grub .97 and isolinux but grub2 is supported. /etc/init.d is used to load tiny core but it does not start Tiny Core it sets up a Linux virtual console to auto log in the user with a re spawn after that the usual shell inits run from /etc/profile. Then the file ".xsession" in /home/tc us called. It starts Tiny Core and the Tiny Core desktop. it then auto starts any custom scripts in home/tc/.X.d. The exact sequence is listed below.

[BootLoader → bzImage → tinycore.gz] → init → inittab → init.d/rcS → tc-config → ( dhcp.sh & tce-setup & restore.sh & bootsync.sh → bootlocal.sh) → init → /root/.profile → /home/tc/.profile →→→ /usr/bin/startx → ( xsetup.sh) → /home/tc/.xsession → ( Xvesa, jwm & wbar & /home/tc/.X.d/*.* )
