Monthly status update about reproducible live-build ISO images

[Roland Clobus]

Hello lists,

here is the 14th update of the status for reproducible live-build ISO 
images [1].

Single line summary: The live images stayed reproducible.

Reproducible status:
* All major desktops build reproducibly with bullseye, bookworm and sid
* Number of patches performed by the live-build script that are not yet 
in sid: zero! (0)

My activities in October:
* Further testing of the live images in openQA, many tests are now green
* The live images are also tested for UEFI secure boot (in addition to 
BIOS and non-secure UEFI)
* The live images are also tests as USB-drive (in addition to CD-ROM boot)
* Some comments in tickets for the snapshot.notset.fr service [10][11]
* I've sent a private mail regarding the live image generation by 
official Debian hardware, more to follow next month

Work to be done:
* Review the results of the generated ISO images in my local openQA instance
* Add a test for the Calamares installer in openQA
* Use a no-network scenario in openQA to test for 100% offline installation
* Live images are not generated officially by Debian yet
** Needs some changes in 'live-setup'
** This will be the next main target
* Adjusting the content of the live-build image
** Make the boot menu more similar to the live-wrapper menu
** Add a 'persistent' option (as seen in Kali)
** Keep the accessibility improvements made in the live-wrapper boot menu
** Verify the package lists
*** e.g. the Debian Reference is installed for es and it, but not en

Unchanged, but low priority due to [7], patch available but not released 
yet:
* texlive-base: Reported differences in the generated ls-R [2]
* texlive-binaries: Randomness in .fmt files due to Lua hash seeds [3]
* texlive-binaries: updmap creates a logfile with the timestamps of 
files that it just has generated [4]

Future plans/ideas:
* Reprotest might be used instead of just 2 builds without a short time 
frame, to capture more variations
* Use disorderfs
* Transfer the special features of the (now disabled) live-wrapper live 
images to live-build
* Start building official live-images again [6][8]

With kind regards,
Roland Clobus
