[Pkg-utopia-maintainers] Bug#1040790: installation-reports: ID in /etc/machine-id and /var/lib/dbus/machine-id mismatch on fresh debian 12 installation

[yogg]

Hi

I created a Debian 12 VM template for our systems and saw that the id's 
did not match (I checked them because I have to recreate them if the 
template gets copied).
So I have not seen any "user-visible symptoms" it was simply luck that I 
checked the files.

At first I thought there was a change and the id's need to be different 
in Debian 12, so I read the docs and found nothing.
Then I asked in IRC and then I created the bug entry.

Regards,
yogg
