Bug#1036371: debian-installer: Blu-ray double-level iso is too large to burn to DLBD disk

[Cyril Brulebois]

loop += debian-cd

Package: debian-installer
Version: 20210731+deb11u8
Severity: important

Dear Maintainer,
* What led up to the situation?
Since the DLBD .iso install neither sets up sources.list with a mirror to
download from nor requests more disks to complete the set, a test of the
DLBD install when using actual Blu-ray disks were in order.
* What exactly did you do (or not do) that was effective (or
ineffective)?
RC3, packaged at 61-62GB per volume, can not be burned into DLBD media.
* What was the outcome of this action?
The test could not even be started.
* What outcome did you expect instead?
The DLBD volumes should be configured at 48-48.5GB. At 61GB, apt still
asks for new packages in /media/cdrom, which cannot possible be
satisfied. See bug#1035476 - editing sources.list as a workaround is, as
apt reminds each time, insecure.
All the packages d-i needs fit in the 25GB set, if not the 16GB one.
Then, the following volumes allow someone with a slow connection (like
mine) to complete an installation from media - if the volumes fit on the
media. Otherwise, the rest of the volumes are not easy to use as a
complete download of the distribution.
Debian Release: (inserted) 12 RC3 --

Just looking at the files on the server, those numbers surprise me...

Could you show exactly what size your images are coming out as, please?

My apologies. I built the DLBD .iso files and then moved them by USB
because I was curious why occasionally more files keep being downloaded
when I the files to scan already include them.
The files I was talking about are the 2023-05-15 build, and I must have
munged them by putting them on USB sticks, In the always-check-again
department, over and out.
