So, you would want the DVD holding the CD ISO images to replace both the DVD ISO image and the CD ISO images? That is going to be very nasty in terms of distribution as one would need a double loop mount for each CD

Is that difficult? I'd not have thought so. I'm sure I've nested loop mounts before.


I'm not saying it is difficult but we're not Joe Average are we?


ISO image to be able to use the installation media as a resource for additional package installation, not to mention the inability of Jigdo to cope with this -which at this point is just a Release Feature I'm the owner of.

I am sure that when I learned to use jigdo some years ago, that it didn't actually care how the file's structured, and that it actually works with tarballs. See http://atterer.net/jigdo/

Richard Atterer might be interested on working with you on this; surely Debian has the same problem.


Debian hasn't got that problem; I've spoken to Richard Atterer and he feels Jigdo is at it's best as it is right now; enough features for what it's supposed to do and still maintainable. Looking at the code I couldn't agree with him more.

The first CDROM though would need to contain another set of metadata which makes opening up the actual repository a pain in the ass -you have mediaid's there, again.

I don't understand.


If you have packages spread over multiple locations, you will need to have repository metadata that also lists the exact location of the package (ergo in this case CD #1, #2, and so on).

Say we built a slightly-modified boot.iso.
Say this boot.iso contains all that's needed to install Fedora/RHEL/whatever. Just not the repos.
Say it has a root directory, /images.
Say this directory _might_ have a collection of ISOs.
If this directory has a collection of .ISOs, then it offers the user the possibility of installing from it. If the collection is incomplete, then it allows changing media during the install process, as it does now for CD installations.


I'm not sure how this differs in having both DVD ISO images (just as we have them now), and CD ISO images available with the releases. I do know having ISO's inside ISO's makes HTTP/FTP installations more difficult as one would now just extract or loop mount the DVD ISO image whereas in this new situation one would have to merge the different CD ISO image's (that you get when loop mounting the DVD ISO image) contents into one large repository.

Kind regards,
