How to generate a .template and .jigdo from an iso image?
Hi. I'm interested in generating the .jigdo and .template from a .iso image. I couldn't find much information on this. It would be a straightforward process, just run "jigdo-file file.iso" and I would have my .jigdo and my .template. The problem is doing like this, my .template has almost the same size of the .iso image. I noticed that the Fedora 11 x86_64 has only 11.1M. My question is how to do that? How to get a .template so small? Where I can get a good documentation about jigdo-file? The official web site[1] it isn't very helpful. Thanks Marcelo [1] http://atterer.net/jigdo/ ___ Fedora-infrastructure-list mailing list Fedora-infrastructure-list@redhat.com https://www.redhat.com/mailman/listinfo/fedora-infrastructure-list

Ignacio, the problem with size is probably because not having files available,
what I used is https://alufis35.uv.es/Creando-plantillas-Jigdo-Jigsaw.html,
translating it:
Having iso original file at path/iso/ and having the iso loopback mounted and
available at path/tree/
We should run
jigdo-file mt -i path/iso/Fedora.iso -j Fedora-DVD.jigdo -t Fedora-DVD.template
—uri fedoramirrors=http://whatevermirror path/tree/
After some checks, trying to download missing files it will create the template
and .jigdo and hopefully, will be a small one ;)

Re: How to generate a .template and .jigdo from an iso image?
Hi I read the man page. It says that I have to specify only one of the options "-i", "-j" or "-t". OK. If I use only -i, my template has the same size of image, then there is no point in using jigdo. There must be something more. My question is how Fedora generates the .template with only 11.1M? The command "jigdo-file -i CentOS-5.3-i386-bin-DVD.iso" it's not enough.

My question is how Fedora generates the .template with only 11.1M? The
command "jigdo-file -i CentOS-5.3-i386-bin-DVD.iso" it's not enough.
Attached is the script Fedora Unity uses to jigdofy it's Re-Spins. Note
the "function jigdofy()" in the top that may just help you get the
syntax right.
Note the double slash in the two directories passed to the "jigdo-file
make-template" command, which functions as a delimiter for jigdo-file,
so that in the --label parameter, we can 'label' the path and then
attach a URI (--uri) to be used in the resulting .jigdo file instead.
$1 is the (fully qualified) path to the .iso image,
$2 is the base architecture for the .iso image (i386, x86_64 or ppc in
our case), and
${version} is the Fedora $releasever (9 or 10 right now).
Also note that /data/os/distr/fedora is a local, full mirror and that
/data/os/archive/fedora is a local, full archive (with package files
that have been removed from the mirror because for example they've
expired and have been superseeded by another update to said package).
