==Fedora Live Images==</pre>
+
  
The Fedora {{Template:DocsDict/BeatVer}}
+
{{Docs_beat_open}}
  release includes several Live ISO images in addition to the traditional installation images.  These ISO images are bootable, and you can burn them to media and use them to try out Fedora.  They also include a feature that allows you to install the Live image content to your hard drive for persistence and higher performance.
+
 
+
=== Available Images ===
+
  
For a complete list of current spins available, and instructions for using them, refer to:
+
[[Category:Docs Project]]
 
+

+
[[Category:Documentation beats]]
 
+
=== Usage Information ===
+
 
+
To boot from the Live image, insert it 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 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.
+
 
+
=== Text Mode Installation ===
+
 
+
You can do a text mode installation of the Live images using the <code>liveinst</code> command in the console.
+
 
+
== Direct Installation ==
+
 
+
You can add 'liveinst' or 'textinst' as a boot loader option to perform a direct installation without booting up the live CD/DVD.
+
 
+
=== USB Booting ===
+
 
+
Another way to use these Live images is to put them on a USB stick.  To do this, 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''.
+
 
+
=== Live USB Persistence ===
+
Support for persistent changes with a Live image exists for Fedora 9. The primary use case is booting from a Live image on a USB flash drive and storing changes to that same device. To do this, download the 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 ''/dev/sdb1'' 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 Live image, plus the overlay, plus any other data to be stored on the media.
+
 
+
=== Tool Changes ===
+
Work has continued to better integrate the Live images with the rest of the system, and improve the tools used for building them. The <code>livecd-creator</code> utility now provides an API for building alternative front-ends, as well as tools for other types of images.
+
 
+
=== Differences From a Regular Fedora Install ===
+
 
+
The following items are different from a normal Fedora install with the Live images.
+
 
+
* Live images provide a subset of packages available in the regular DVD image. Both connect to the same repository that has all the packages.
+
* SSH is disabled by default. SSH is disabled because the default username in the Live images does not have any password. However, installation to hard disk prompts for creating a new username and password.
+
* 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 Packages'' tool, <code>yum</code>, or the other software management tools.
+
* Live images do not work on <code>i586</code> architecture.
