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. Tilgjengelige avbilder
For a complete list of current spins available, and instructions for using them, refer to:
7.2. Bruksinformasjon
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.

7.3. Installasjon i tekst-modus
Du kan foreta en installasjon av Live-avbildet i tekst-modus ved å bruke kommandoen liveinst på kommandolinjen.
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. Starte opp fra USB
En annen måte å bruke disse Live-avbildene på, er å legge dem på en USB-minnepinne. For å gjøre dette, installer livecd-tools-pakken fra utviklingspakkelageret. Kjør så skriptet livecd-iso-to-disk:
/usr/bin/livecd-iso-to-disk /path/to/live.iso /dev/sdb1
Erstatt /dev/sdb1 med den partisjonen hvor du vil legge avbildet.
Dette er ikke en destruktiv prosess; all data du allerede har på USB-minnepinnen blir tatt vare på.
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
Erstatt /dev/sdb1 med den partisjonen hvor du vil legge avbildet.
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. Forskjeller fra en vanlig Fedora-installasjon
Følgende saker er forskjellig fra en normal Fedora-installasjon med et Live-avbilde:
Live-avbilder tilbyr et utvalg av pakker som er tilgjengelig i DVD-utgaven. Begge kobler til samme pakkelager som har alle pakkene.
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
yumor the other software management tools.Live-avbilder fungerer ikke på
i586-arkitekturen.
