|
| |
| == Getting started ==
| |
|
| |
| To create a live image, the '''livecd-creator''' tool is used. Super user privileges are needed. The tool is more or less self-documenting, use {{command | livecd-creator --help}} to see options.
| |
|
| |
| The '''livecd-creator''' tool is part of the <code>livecd-tools</code> package. If it is not installed on your system, add it with [[dnf|DNF]] or [[yum|YUM]]:
| |
|
| |
| <pre>
| |
| su -c 'yum install livecd-tools spin-kickstarts' #Versions prior to Fedora 22
| |
| or
| |
| su -c 'dnf install livecd-tools spin-kickstarts' #Fedora 22 and beyond
| |
| </pre>
| |
|
| |
| If you are interested in localized (i.e. translated into other languages) live CD files, install also '''l10n-kickstarts'''.
| |
|
| |
| == Configuring the image ==
| |
|
| |
| The configuration of the live image is defined by a file called ''kickstart''. It can include some basic system configuration items, the package manifest and a script to be run at the end of the build process.
| |
|
| |
| For the Fedora project, the most important live image configurations files are:
| |
|
| |
| * '''[https://git.fedorahosted.org/cgit/spin-kickstarts.git/tree/fedora-live-base.ks fedora-live-base.ks]''' : The base live image system (included in the 'livecd-tools' package).
| |
| * For ''Fedora 20 and earlier'': '''[https://git.fedorahosted.org/cgit/spin-kickstarts.git/tree/fedora-livecd-desktop.ks fedora-livecd-desktop.ks]''' : Complete desktop with applications and input/output support for all supported locales in Fedora (this one is part of the 'spin-kickstarts' package) - despite the name, this is the kickstart that generates the ~1GB-sized images for recent releases.
| |
| * For ''Fedora 21 and later'': '''[https://git.fedorahosted.org/cgit/spin-kickstarts.git/tree/fedora-live-workstation.ks fedora-live-workstation.ks]''' - this is the [[Workstation]] product configuration.
| |
|
| |
| ''kickstart'' files for other spins (e.g. Fedora Electronics Lab) can be found in {{filename|/usr/share/spin-kickstarts/}} after installing the 'spin-kickstarts' package. These pre-made configuration files can be a great place to start, as they already have some useful pre and post-installation scripts.
| |
| [[Image:system-config-kickstart.png|thumb|system-config-kickstart]]
| |
| You can create a customized ''kickstart'' file by running {{command | system-config-kickstart}}. Note that you might have to install the package first with {{command|su -c "dnf install system-config-kickstart"}} in Fedora 22 and beyond or {{command|su -c "yum install system-config-kickstart"}} in earlier versions of Fedora. This tool is mainly intended for generating kickstart files for automated installs, not live images, so the output will probably not be usable without editing, but it may help you to generate particular kickstart directives. Remember to add the line:
| |
| <pre>
| |
| %include /usr/share/spin-kickstarts/fedora-live-base.ks
| |
| </pre>
| |
| at the beginning of your ''kickstart'' file to include the base live configuration.
| |
|
| |
| {{admon/tip || See [[Anaconda/Kickstart#Creating_the_Kickstart_File | Creating a ''kickstart'' file]] for advanced information regarding making your own custom ''kickstart'' file.}}
| |
|
| |
| == Making the image ==
| |
|
| |
| To make the image, simply issue the following command:
| |
| <pre>
| |
| livecd-creator --verbose \
| |
| --config=/path/to/kickstart/file.ks \
| |
| --fslabel=Image-Label \
| |
| --cache =/var/cache/live
| |
| </pre>
| |
|
| |
| The name given by ''--fs-label'' is used:
| |
|
| |
| * as a file system label on the ext3 and iso9660 file systems (As such, it's visible on the desktop as the CD name).
| |
| * in the ''isolinux'' boot loader.
| |
|
| |
| If you have the repositories available locally and don't want to wait for the download of packages, just substitute the URLs listed in the configuration file to point to your local repositories.
| |
|
| |
| {{admon/note | Making a 32-bit spin ISO on a 64-bit machine| If you have an x86_64 machine you're building on but you want a 32-bit happy iso image, add the following before your livecd-creator command:
| |
| <pre>setarch i686 livecd-creator [...]</pre>
| |
| }}
| |
|
| |
| == Examples ==
| |
|
| |
| === Spinning the fedora desktop ===
| |
|
| |
| The following command:
| |
|
| |
| <pre>
| |
| livecd-creator --verbose \
| |
| --config=/usr/share/spin-kickstarts/fedora-live-workstation.ks \
| |
| --fslabel=Fedora-LiveCD \
| |
| --cache=/var/cache/live
| |
| </pre>
| |
|
| |
| will create a live CD called "Fedora-LiveCD" using the '''fedora-live-workstation.ks''' configuration file.
| |
|
| |
| === A Barebones Live CD ===
| |
|
| |
| The command
| |
|
| |
| <pre>livecd-creator --verbose \
| |
| --config=/usr/share/doc/livecd-tools-`rpm -q livecd-tools --qf "%{VERSION}"`/livecd-fedora-minimal.ks \
| |
| --cache=/var/cache/live
| |
| </pre>
| |
|
| |
| will create a live CD that will boot to a login prompt.
| |
|
| |
| {{Admon/tip | Barebones Live CD does not support login capability. | Since no configuration is done, the user will not be able to login to the system as the root password is not set/cleared.}}
| |
|
| |
| == Testing your Live CD using KVM or qemu ==
| |
|
| |
| [[Image:Screenshot_qemu_gtk3.png|thumb|QEMU running Fedora 17]]
| |
|
| |
| As root:
| |
|
| |
| qemu-kvm -m 2048 -vga qxl -cdrom filename.iso
| |
|
| |
| If you do not have [[Wikipedia:Kernel-based_Virtual_Machine | KVM]] support, you have to use qemu instead
| |
|
| |
| qemu-system-x86_64 -m 2048 -vga qxl -cdrom filename.iso
| |
|
| |
| Replace '''filename.iso''' with the name of your created Live CD image and '''qemu-system-x86_64''' with an appropriate qemu binary for the target system, e.g '''qemu-system-i386'''.
| |
|
| |
| {{Admon/tip || Be sure to '''"yum install kvm qemu"''' as root for releases before Fedora 11. Fedora 11 has merged kvm and qemu into a single package. Just installing qemu package is enough.}}
| |
|
| |
| == Using your new live image ==
| |
|
| |
| You can [http://docs.fedoraproject.org/readme-burning-isos/ burn your image directly to a CD or a DVD] if it fits, or you can [[How_to_create_and_use_Live_USB | write it to a USB stick]].
| |
|
| |
| {{admon/install | Installing the Live image to the hard drive | As of Fedora 7, anaconda has support for doing an installation from a live image. To use this, double click on the ''Install to Hard Drive'' item on the desktop or run
| |
|
| |
| <pre>
| |
| /usr/bin/liveinst
| |
| </pre>
| |
|
| |
| if you don't have such an icon. However, because of the way {{command|livecd-creator}} works, it is not possible to choose a different set of packages or a different filesystem during installation.}}
| |
|
| |
| == Live Image Media Verification ==
| |
|
| |
| The live image can incorporate functionality to verify itself. To do so, you need to have '''isomd5sum''' installed both on the system used for creating the image and installed into the image. This is so that the '''implantisomd5''' and '''checkisomd5''' utilities can be used. These utilities take advantage of embedding an md5sum into the application area of the iso9660 image. This then gets verified before mounting the real root filesystem.
