Hello lists,

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

* The frequency for testing bullseye (stable) has been reduced to montly
* Bookworm (testing) is now tested weekly and sid (unstable) daily [2]
** Two Perl sorting issues have been found in dictionaries-common [3][4]
** I'll need feedback from the maintainer about the intended behaviour 
before a patch can be written
** Diffoscope needs about 2 hours (!) to find the differences in the 
squashfs images that are embedded in the ISO images
* I've looked at OpenQA for testing the freshly generated live images, 
some basic functionality tests will run soon

Future plans/ideas:
* I've initiated a discussion on a method for recording the 
configuration used by live-build in September
** Next step: test some scenarios and write a proposal
* Reprotest might be used instead of just 2 builds without a short time 
frame, to capture more variations
* I will test the functionality of the generated ISO images using OpenQA
* Long term: When live-build images are working fine, the work could be
extended to other images, e.g. the live-wrapper images, the netinst
images or perhaps even Docker images
* When it is ready, switch to

With kind regards,
Roland Clobus
