===Larger than CD size===
+
{{Admon/note |  Fedora 13 onwards, Fedora Desktop Live image is larger than a CD; you must use USB or DVD media or choose a smaller spin from: http://spins.fedoraproject.org| }}
+
 
+
Rationale:
+
* The Gnome Desktop Spin targets the majority of users as a group; though it is most commonly downloaded, it cannot be optimized to be the best solution for ''everyone'' because different people have different needs.
+
* The majority of users have USB or DVD media available, and the price of these media is competitive with CDs (or better, considering that USB sticks are highly reusable).
+
* Expanding to beyond 700MB allows the inclusion of software such as OpenOffice, which is a critical piece of a modern, widely useful Live distribution.
+
* For users who cannot boot from USB or DVD media, there are several other options, including:
+
** Smaller-than-CD image (boot.iso) which can install Gnome Desktop to a hard drive via the network
+
** Multi-CD installer which can install Gnome Desktop to a hard drive
+
** Hard drive install method
+
** Other spins which will still fit on a CD if a LiveCD is still necessary
+
** The ability to create a custom spin using Revisor (see [[How to create and use a Live CD]]) if a Gnome-based LiveCD is absolutely needed.  Individual users can start with the Gnome Desktop spin and remove packages until it is the desired size; the included packages are specified in a downloadable kickstart file.

In the future, any group of Fedora contributors can come together to publish a separate Gnome Desktop CD spin if there is sufficient interest.

Download and Create Live image or Live USB

To download a pre-built Fedora Live image, visit the download page. Then you can either:

If you want to build and then burn your own custom ISO, see How to create and use a Live CD.

Advantages and Limitations

Benefits:

  • You can demonstrate features or try out a release, including testing hardware functionality, before hard disk/SSD installation.
  • Live USB/CD/DVD installation is faster than regular installation. Live USB/SD installation typically takes only a few minutes and can be configured with persistent storage.
  • You can use Live CD technology for backup and recovery of your installed hard drive.

Limitations:

  • It is not possible to choose packages during installation. Live images typically have fewer packages than a regular installation image.
  • It is not possible to do an upgrade via the Anaconda installer. If you have a separate /home partition, you can just not format it during the installation and thus preserve your settings and /home content.
  • It is not possible to choose a non-default filesystem.
  • Once you shutdown a computer running from a Live CD, you will lose any settings or packages installed, but Live USB/SD installations may be configured with persistent storage.

Fedora Live image features

Current features:

  1. A booted Live CD uses a temporary, in-memory, read-write rootfs, so it's possible to install software for use while the Live CD is running.
  2. Data persistence options available on Live USB/SD installations.
  3. Install to hard disks or USB/SD drives.
  4. Uses SELinux in enforcing mode and other security features by default.
  5. Includes best of breed software on the media.
  6. Stay as close to a normal desktop install with regard to features, or try specialized Spins.
  7. Ability to create normal CD-ROM and CD-R media (less than 700 MB) or DVD images.
  8. Make it easy to do a derived Live CD with your own repositories, packages, and artwork.
  9. API used by LTSP, appliance creator and others

Communicate

Fedora Live image users and developers can participate and contribute in the discussions happening in the Fedora Live CD list.

(predecessor list archives)

Finding the Code

The source code for the Live CD tools is maintained in git. The repository is at 'git://git.fedorahosted.org/livecd' and can be browsed via the cgit interface . You can install it easily by installing the 'livecd-tools' package.

Kickstart files are in the spin-kickstarts.noarch package.

Hard Drive Installation

The ability to install to a hard drive is available releases since Fedora 7. After the live media boots, click on the install icon on your desktop to start the installation. Installation from live image requires that GRUB and the /boot directory be installed onto a drive with an MSDOS partition label, or that the current machine supports EFI booting. If a pc-clone machine has only GPT hard drives, then you may need to use something such as a USB2.0 flash memory device (with an MSDOS partition label) as an intermediate destination.

In Fedora 15, instead of clicking the desktop icon, choose Applications->System Tools->Install to Hard Drive from the menu along the top of the screen.
