The [[Games Spin]] provides a Live DVD with a sampling of the best games available in Fedora.
 
 
For electronic designers, the [http://chitlesh.fedorapeople.org/FEL Fedora Electronic Lab] spin provides a complete toolchain for IC designers.
 
 
The Fedora Spins SIG (http://fedoraproject.org/wiki/SIGs/Spins) is continuously developing specialized Live images for specific purposes.
 
 
<!--
 
The Fedora {{Template:DocsDict/BeatsVer}} release includes several Fedora Live ISO images in addition to the traditional installation images.  Fedora Live ISO images are intended to make it easy for you to create bootable CD media containing this Fedora release and a small selection of applications. Once booted, the Fedora Live image also includes a feature that allows you to install the Fedora Live image content to your hard drive for persistence and higher performance. It is an excellent way to ''test drive'' the Fedora Linux operating system on hardware prior to committing to a permanent installation.
 
 
 
=== Available Images ===
 
 
For a complete list of current spins available, and instructions for using them, refer to:
 
 
http://fedoraproject.org/wiki/CustomSpins
 
 
=== Usage Information ===
 
 
To boot from the Fedora Live image, insert the media into your computer and restart. To log in and use the desktop environment, enter the username <code>fedora</code>.  There is no password on this account.  The GNOME-based Fedora Live images automatically login after one minute, so users have time to select a preferred language. After logging in, if you wish to install the contents of the Live image to your hard drive, click on the '''Install to Hard Drive''' icon on the desktop.
 
 
=== Checking Your Media ===
 
 
For Fedora Live media, press any key during the initial boot countdown to display a boot option menu. Select Verify and boot to perform the media test.
 
Perform this test for any new Live medium.
 
 
=== Text Mode Installation ===
 
 
A text mode installation of the Fedora Live images is available by using the <code>liveinst</code> command in the console.
 
 
=== USB Booting ===
 
 
Another way to use these Fedora Live images is to put them on a USB stick.  To do this, you can use <code>liveusb-creator</code> graphical interface. Use ''Add/Remove Software'' to search and install <code>liveusb-creator</code> or install using <code>yum</code>:
 
 
<pre>
 
su -c 'yum install liveusb-creator'
 
</pre>
 
 
A Windows version is available as well to enable users to easily try out or migrate to Fedora.
 
 
You can also use the command line interface. Install the <code>livecd-tools</code> package from the repository.  Then, run the <code>livecd-iso-to-disk</code> script:
 
 
<pre>/usr/bin/livecd-iso-to-disk /path/to/live.iso /dev/sdb1
 
</pre>
 
 
Replace ''/dev/sdb1'' with the partition where you want to put the image.
 
 
This is ''not'' a destructive process; any data you currently have on your USB stick ''is preserved''.
 
 
==== Persistent Home Directory ====
 
 
Support for keeping a persistent <code>/home</code> with the rest of the system stateless has been added for Fedora 10.  This includes support for encrypting <code>/home</code> to protect your system in the case where your USB stick is lost or stolen.  To use this, download the Live image and run the following command:
 
 
<pre>livecd-iso-to-disk --home-size-mb 512 /path/to/live.iso /dev/sdb1
 
</pre>
 
 
Replace <code>/dev/sdb1</code> with the partition where you want to put the image.
 
 
Replace <code>512</code> with the desired size in megabytes of the persistent <code>/home</code>.  The <code>livecd-iso-to-disk</code> shell script is stored in the <code>LiveOS</code> directory at the top level of the CD image. The USB media must have sufficient free space for the Fedora Live image, plus the <code>/home</code>, plus any other data to be stored on the media.  By default, this encrypts your data and prompts for a passphrase to use.  If you want to have an unencrypted <code>/home</code>, then you can specify <code>--unencrypted-home</code>.
 
 
Note that later runs of <code>livecd-iso-to-disk</code> preserve the <code>/home</code> that is created on the USB stick, continuing to use it even if you change your Live image.
 
 
==== Live USB Persistence ====
 
 
Support for persistent changes with a Fedora Live image exists for Fedora 9 and later. The primary use case is booting from a Fedora Live image on a USB flash drive and storing changes to that same device. To do this, download the Fedora Live image and then run the following command:
 
 
<pre>livecd-iso-to-disk --overlay-size-mb 512 /path/to/live.iso /dev/sdb1
 
</pre>
 
 
Replace <code>/dev/sdb1</code> with the partition where you want to put the image.
 
 
Replace <code>512</code> with the desired size in megabytes of the persistent data, or <code>overlay</code>.  The <code>livecd-iso-to-disk</code> shell script is stored in the <code>LiveOS</code> directory at the top level of the CD image. The USB media must have sufficient free space for the Fedora Live image, plus the overlay, plus any other data to be stored on the media.
 
 
==== Booting a Fedora Live from USB on Intel-based Apple Hardware ====
 
 
Fedora 10 includes support for putting the Live image onto a USB image and then booting it on Intel processor-based Apple hardware.  Unlike most x86 machines, this hardware requires reformatting the USB stick.  To set up a USB stick, run this command:
 
 
<pre>/usr/bin/livecd-iso-to-disk --mactel /path/to/live.iso /dev/sdb1
 
</pre>
 
 
Replace <code>/dev/sdb1</code> with the partition where you want to put the image.
 
 
Note that all of the other arguments for the <code>livecd-iso-to-disk</code> tool as described above can be used here as well.
 
 
=== Differences From a Regular Fedora Install ===
 
 
The following items are different from a normal Fedora install with the Fedora Live images.
 
 
* Fedora Live images provide a subset of packages available in the regular DVD image. Both connect to the same repository that has all the packages.
 
* The SSH daemon <code>sshd</code> is disabled by default. The daemon is disabled because the default username in the Fedora Live images does not have a password. However, installation to hard disk prompts for creating a new username and password.
 
* Fedora Live image installations do not allow any package selection or upgrade capability since they copy the entire file system from media or USB disks to the hard disk. After the installation is complete, and your system has been rebooted, you can add and remove packages as desired with the ''Add/Remove Software'' tool, <code>yum</code>, or the other software management tools.
 
* Fedora Live images do not work on <code>i586</code> architecture.
