The Fedora 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.

7.1. Available Images

For a complete list of current spins available, and instructions for using them, refer to:

http://fedoraproject.org/wiki/CustomSpins

7.2. 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 fedora. Hit Enter at the password prompt, since there is no password on this account. The Live images do not automatically login so users can 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.

[Poznámka] No i586 Support

The i686 Live images will not boot on an i586 machine.

7.3. Text Mode Installation

You can do a text mode installation of the Live images using the liveinst command in the console.

7.4. 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.

7.4.1. USB Booting

Another way to use these Live images is to put them on a USB stick. To do this, install the livecd-tools package from the development repository. Then, run the livecd-iso-to-disk script:

/usr/bin/livecd-iso-to-disk /path/to/live.iso /dev/sdb1

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.

7.4.2. Live USB Persistence

Work has continued to better integrate the Live images with the rest of the system, and improve the tools used for building them. The livecd-creator utility now also provides an API for building alternative front-ends as well as tools for other types of images.

The initial work to support persistent changes with a Live image has also landed. 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:

livecd-iso-to-disk --overlay-size-mb 512 /path/to/live.iso /dev/sdb1

Replace /dev/sdb1 with the partition where you want to put the image.

Replace 512 with the desired size in megabytes of the persistent data, or overlay. The livecd-iso-to-disk shell script is stored in the LiveOS 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.

7.4.3. 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 and NetworkManager is enabled by default in the Live images. SSH is disabled because the default username in the Live images does not have any password. Installation to hard disk prompts for creating a new user name and password however. NetworkManager is enabled by default since Live images target desktop users.

  • Live image installations do not allow any package selection or upgrade capability since they copy entire the filesystem from media to hard disk or USB disks. After the installation is complete and rebooted, packages can be added and removed as desired with yum or the other software management tools.

  • Live images do not work on i586 architecture.
