This page shows you how to build an ISO of Rawhide that you can use for testing.
The rest of this tutorial requires that you open a root shell. Open a terminal and run the command
su -, and provide the root password.
Making a local copy of Rawhide
If you don't have Rawhide available on a fast, local link, you may want to mirror it locally using
mkdir -P /var/www/fedora/linux/development/x86_64/os cd /var/www/fedora/linux/development/x86_64/os rsync -Pavy --delete-after <MIRROR_NEAR_YOU>::fedora-linux-development/x86_64/os .
Note that these commands assume you are interested in testing the
x86_64 (64-bit) architecture. Substitute
i386 as needed for 32-bit architecture.
This section shows the procedure to make a DVD-sized ISO image from the Rawhide repository.
- You must be running Rawhide, or use
to continue. Refer to the Pungi documentation for more information. One easy way to proceed, since you presumably have a Rawhide mirror available (see above), is to install Rawhide in a virtual guest machine.
- You can use the same tools that Fedora Release Engineering uses to make a DVD. First, install the
yum install pungi
- Change directory to an area with gobs of free space. Use the
df -hcommand to find a location if needed.
- Download the current kickstart file for Rawhide.
curl -o rawhide-fedora.ks http://git.fedorahosted.org/git/pungi.git?p=pungi.git;a=blob_plain;f=share/rawhide-fedora.ks;hb=HEAD
- Edit the
repocommands in the
rawhide-fedora.ksfile to point at your local mirror, if needed. If the mirror is on your hard disk as above, for example, use this command in the kickstart file:
repo --name=rawhide --baseurl=file:///var/www/fedora/linux/development/$basearch/osIf you do not make these changes, the packages for Rawhide will be downloaded from a nearby official Fedora mirror. Note that this could take several hours even on a fast broadband connection.
- Make the DVD image:
pungi --nosource --nosplitmedia --nodebuginfo --all-stages -c rawhide-fedora.ks
Testing a release candidate
Special release candidates are made available through the alt.fedoraproject.org staging site. You can simply download a release candidate from this site, although the transfer speed generally means you must wait several hours for an ISO image.
However, if you've already built a DVD ISO image from Rawhide, and Rawhide is reasonably close to the state of the release candidate, you can use
rsync to "upgrade" your Rawhide DVD ISO image to the release candidate. The resulting DVD ISO image can be verified as identical using the
- Get the official file name of the DVD from the mirror. Note the directory location and the file name.
- Rename your DVD ISO image to the same name as the official file.
cd 20090325/x86_64/iso mv Fedora-20090325-x86_64-DVD.iso Fedora-11-Beta-x86_64-DVD.iso
rsyncto download the required bits to match your DVD to the original. The switches below deliver stats as you download, and effectively minimize the amount of downloading. Note that the location shown is an example only.
rsync -Pavy alt.fedoraproject.org::alt/stage/11-Beta.rc3/Fedora-11-Beta-x86_64-DVD/Fedora-11-Beta-x86_64-DVD.iso .
sha256sumto test the image for integrity. The resulting checksum should be identical to that shown in the
*CHECKSUMfile that accompanies the image on the staging site.
