jigdo

[Michael A. Peters]

Has Fedora considered using jigdo for distribution of the iso's?

It works very well for fetching debian iso's - and you can use mirrors
that don't have iso files - as the iso files themselves are generated on
the end user machine.

It would also mean that stable versions of fedora could have the iso's
updated as package bug fixes come out, so that 3 months after release -
a user doesn't spend hours of bandwidth getting CD's that are going to
require additional bandwidth to bring to patch level.

Anaconda would I think need to know about such updates too. The other 
negative is that it means different people get different CD images and
it may be harder to know which work and which fail

It might be somethig interesting to look at for FC3

I believe that , in the first moments , jigdo could be used only for the 
release isos. And the creating of updated images should be discussed a 
lot more.  Updated images gives us a shorter installation (because the 
system is already updated) , but it makes harder to know exactly which 
packages are installed in someone's system. This could make difficult to 
help people on fedora-list , because , most of the time , people forget 
to mention the version of the software involved... This is easy to 
overcome (explaining to users to always post the version of the software 
causing problems or , if they forget to do so , asking them the 
version).  Also , one thing has to be considered: what will be needed to 
adapt anaconda to work with these updated images? This has to be tested 
a lot , so I believe it may be available only in FC3...

But maybe jigdo could be used on FC2 to distribute the release isos.. 
This could save a few gigabytes from the mirrors... For FC2 , there will 
be the standard CD images and maybe DVD images (I hope ;) ). This sums 
up to 8GB of images. Then , multiply it by 2 (i386 and x86_64 
images).... 16GB of  images... Considering that all mirrors carry the 
directory structure available at download.fedora.redhat.com , then , 
this shouldn't be necessary... The only thing needed is the .jigdo and 
.template files (for CDs , the .template file is about 30MB.  For DVDs , 
the .template file is about 200MB).

Now , only one thing bothers me. I just saw on the page on debian.org 
about jigdo that currently DVD images cant be downloaded in Windows... 
I'm going to test it on windows to see it was already fixed... If this 
can be corrected , then jigdo will be perfect for both end-users (who 
will be able to download from a fast mirror nearby) and for mirror 
admins (who will save a lot of disk space).

Just my R$0,02 ;)

Packages are already available for jigdo on RHL 8.0/9, FC1/2:
