How to create DVD iso

[c-clone]

Recently I got myself mandriva 2007.1 which came in 2 double layers DVDs. DVD 1 contains i586 and x86_64. Now how do i create a seperate dvd with just x86_64 packages? Can anybody refer me to any page? Thanks

I'm not an expert in this area, but as far as I'm concerned, the only special thing about a Mandriva CD/DVD is that it is bootable (ie: the BIOS can launch it). This property is set at "burn" time by pointing the burning software to a bootable floppy image found in the DVD contents.

 

My "naïve" answer, would be to dump the DVD contents somewhere, eg: /tmp/MdvDVD, and then remove every package for the i586 architecture, which should roughly halve the size of the DVD, and finally burn the DVD, not forgetting to point the software (eg: K3B) to the right floppy image so that it is bootable.

 

However:

- I never tried such a thing. It may fail.

- I'm not sure it will fit on a 4GB DVD because Mandriva media are well known to be well filled (almost over-burnt), and removing all i586 does probably not quite result in half the initial size; but then, a single-layer DVD is more than half a double-layer DVD, so...

- I'm not sure it is a good idea. As far as I know, you need the i586 packages for a few things; for instance Flash plugin, and the libraries needed by it probably.

ISOMaster will do it for you (removing the x86 files from the DVD ISO, while keeping the boot record intact).

However, I cannot know if the installer will run properly after that, as I haven't the slightest idea about the DVD's structure details.
