How to burn all of Debian onto BLU-RAY

[gro...@cyberdude.com]

Hi,
I've downloaded all 16 DVDs of 10.2, the .iso files are on my HD right now. Now what I want to do, is to burn all that data to some Blu-Ray discs that I have (I guess I'll need about 4 of them, at 25 gigs each?), NOT DVDs. How do I do this, ie. "combine" these 4.whatever gig files into ONE big 25 gig file (well, multiple ones, for the multiple Blu-Ray discs) that the Blu-Ray disc, the first one, can boot from, and from then onwards, can install the rest of Debian from?

Thanks.

Use jigdo to build the 4 blu-ray images.

Er - how do I use it to build the Blu-Ray images FROM the DVD images? All the docs talk about how to build the *DVD images* themselves....? :(

why not on a single USB 64Gb pendrive?

I've never used Jigdo but at least
https://help.ubuntu.com/community/JigdoDownloadHowto seems to indicate
it will ask what images you already have.

I did not say you could use the DVD images to build the blu-ray images.
Jigdo uses a Debian mirror to download the packages and build the
images. Unless you can use the DVD images to build a local mirror or
populate jigdo's temporary download directory, I am afraid they are useless.

because I don't have 1, and because I want a PERMANENT (ie. NON-WRITABLE TO) copy!

I don't follow you - I have used jigdo to d/l the iso files I *have*, all complete - how will it help me make the BLU-RAY images out of them? THAT was my question....

[The Natural Philosopher]

It wont. If you want to get to there, you don't start from there.

I wouldn't try the impossible.

DVD images go to DVD disks.
Blu-Ray images go to Blu-Ray disks.

And that's what I tried to answer. This part from the link above led me
to believe you could:

"Supply previous CD image

Jigdo will then download a copy of the .jigdo file and prompt you for
any previous images you have to base the download from. Here you can
point Jigdo to an existing burned copy of the CD image, or loop-mounted
ISO image (see MountIso). (eg. /media/cdrom or /media/cdimage)"

Are you saying this is wrong and Jigdo can't used like that?

[The Natural Philosopher]

At some level presumably one mounts the ISOs extracts the files builds a
file tree for one big image and burns a new ISO.

Yes. As I understand it, Jigdo can do exactly this, specifically in such
a way that the directory structure is what Debian installer expects and
so the resulting BDs can be used for installaing.

[gro...@cyberdude.com]

Yes, HOW please? How do I tell it to build *Blu-ray* size images to burn??

[Anssi Saari]

Point Jigdo to the jigdo file for creating BD images. See
https://www.debian.org/CD/jigdo-cd/ and
https://cdimage.debian.org/debian-cd/current/amd64/jigdo-bd/

Er - are you sure that won't start getting it from the net all over again or something? How do I tell it I already *HAVE* 16 DVD .isos? It won't delete them or something in a moment of lunacy, will it?

[Bobbie Sellers]

Computer programs do not have moments of Lunacy, users, coders and
other human agencies demand things that antithetical to the computer
program.
I have downloaded plenty of stuff that was useless. You might
have done that. Read the documents and see if you can point 'jigdo' at
the directory full of your downloads. You might have to disassemble the
DVD iso files to make the downloads useful.

Personally I think you are sort of reaching to create BD boot images.
May your reach not exceed your grasp.

Jigdo does not care about your other ISO images. Quoting my own previous
reply :

"I did not say you could use the DVD images to build the blu-ray images.
Jigdo uses a Debian mirror to download the packages and build the
images. Unless you can use the DVD images to build a local mirror or
populate jigdo's temporary download directory, I am afraid they are
useless."

Maybe you can extract *.deb files from the DVD ISO images into jigdo's
temporary dowload directory.

No. Information on the topic seems to indicate it won't if that's your
wish.

I already answered that. OTOH, Pascal Hambourg contradicts me on this so
I suppose you're on your own. I don't want to be involved any further.

I have no idea.

[Carlos E. R.]

Hardlink the isos on another directory, and then it can not delete both.
