===Introduction===
jigdo is a method of downloading CD and DVD images over the Internet (and other large files) and is used by Debian and Ubuntu when new releases are created. jigdo files contain a list of the files that need to be included in the new CD or DVD ISO image and you can get the files from local sources and over the Internet. This means when you want to create ISO images for updated versions of Debian, you only need to download the changed files. This saves both bandwidth and and time.

You need to download and install the correct RPM file from http://dag.wieers.com/rpm/packages/jigdo/ . The choices currently available are for RHEL/CentOS 1 through 5 (they're the ones labelled eg jigdo-0.7.3-1.el5.rf.i386.rpm where the text in bold indicates Enterprise Linux 5), Red Hat 9, and Fedora 1 through 3. There are also source RPMs available.

===Generic Use of jigdo by mirroring repository on SME Server===
This is generic instruction when you need to build an iso for test purpose on a SME Server (what else). Before formally releasing an iso on SME Server mirrors, the developers work on a pre-release to test and debug it, so you have to use jigdo to create the iso, the aim being to test it .<br />
First you have to verify that jigdo is installed on your SME server, see instructions [[JIGDO_-_create_SME_Server_ISOs#Installing_jigdo_on_CentOS_and_RHEL|above]] or below for [[JIGDO_-_create_SME_Server_ISOs#Getting_SME_8.1_Beta_2|debian]].
* If you want to build an iso of our marvellous work, you need to download packages from our mirrors. Firstly, make a couple of folders to organize your work (choose the right SME Server needed) :
mkdir -p /root/jigdo/sme9
or for SME Server 8
mkdir -p /root/jigdo/sme8
* Download all contents from the repos (see below), best to make a cup of coffee, it can take some time...This is an example of what you have to do to build a sme9.0beta3, you should take a look to the repository to adapt a new url. This command Line can update rpm in your folder, there is no need to download again which is already downloaded.
rsync --progress -aHS --partial --delete-after rsync://mir1.ovh.ca/smeserver/releases/testing/9.0beta3/ /root/jigdo/sme9
or for SME Server 8
rsync --progress -aHS --partial --delete-after rsync://mir1.ovh.ca/smeserver/releases/testing/8.1beta3/ /root/jigdo/sme8
* Once finished you need to go to the right folder
cd /root/jigdo/sme9/iso/x86_64/
or for SME Server 8
cd /root/jigdo/sme8/iso/x86_64/
* Perform this command
jigdo-lite --noask --scan ../../smeos/x86_64/ *.jigdo
of course you have to adapt the architecture which you want to build (i386 or x86_64). '''A known issue is that jigdo fails with a code 3 if an ISO is already present in its current folder.'''
=== Getting SME 8.1 Beta 2 on Debian ===
The [http://atterer.org/jigdo/debian-jigdo-mini-howto mini-HOWTO for jigdo] describes it's format and justification for use.
* Download the jigdo file:
mkdir -p /home/dluser/smeserver
wget http://mirror.contribs.org/releases/testing/8.1beta2/smeos/i386/smeserver-8.1beta2-i386.jigdo
* Since it is only beta, edit the '''Servers''' section for the '''SMEmirror''' parameter to be:
SMEmirror=http://mirror.contribs.org/releases/testing/8.1beta2/smeos/i386/
* When it becomes final, the above step will not be necessary as the '''/8.1beta2/''' folder will become '''/8/'''.
* Trying to get it in debian will entail the install of [https://help.ubuntu.com/community/JigdoDownloadHowto jigdo-file]
apt-get install jigdo-file
* Get the ISO using '''jigdo-lite''' (yes, not ''jigdo-file'')
jigdo-lite smeserver-8.1beta2-i386.jigdo
* On 2013-10-15, when the ISO was built, it was 727,961,600 bytes in length and had the following MD5:
a509d21d476f66b9d27135599b3e6936 smeserver-8.1beta2-i386.iso
* The end log was

Finished!
The fact that you got this far is a strong indication that `smeserver-8.1beta2-i386.iso'
was generated correctly. I will perform an additional, final check,
which you can interrupt safely with Ctrl-C if you do not want to wait.
OK: Checksums match, image is good!

'''Note:''' Not working because jidgo file points to 8, not 8rc1. Editing the file <tt>smeserver-8.0rc1-i386.jigdo</tt> for correct path for SMEmirror under the Servers section allows completion of ISO downloading.
Should work for final release....
