Using a recent .jigdo file produced by the Fedora Unity folks for a Fedora 10 respin, I constructed two jigdo files for CentOS 5.3, one for each arch... but the could be combined into a single file if desired. The sample I used was:
You can find the two files I created here:
Each one has multiple [Image] defs for all of the CDs and the DVD so that you can download one jigdo and then decide what which CD(s) or DVD you want to create.
I just have some questions about some of the things found in the Fedora Unity .jigdo that don't seem to be documented in the jigdo-file man page. For example they have a [Mirrorlists] section and I'm not sure what that is about because they also have a lengthy [Servers] section.
In the two .jigdo files I mention about the URLs for [Server] are static but it would be nice to have a URL that would dynamically rotate between various mirror sites to spread the download across more of the CentOS mirrors... rather than the handful of mirror URLs I put in there... which I'm thinking is what the [Mirrorlists] thing is all about?!?
So far as not getting the jigdo-file command line just perfect... his recipe did work once I discovered the i386 reference that should have been $arch... and altered the rsync --exclude for my different source directory... but to construct my more complex, multiple [Image] .jigdo files I had to cheat and use a text editor. To get all of the parts I simply:
grep '=CentOS:' *i386*.jigdo | sort | uniq > parts-i386.txt
grep '=CentOS:' *x86_64*.jigdo | sort | uniq > parts-x86_64.txt
So far I've really enjoyed learning about jigdo but want to learn more. :)
