[systemd-devel] What information does machine-id leak?

[Bryan Quigley]

Hi there,

I see that there is a concern that we need to keep machine-id private
(and local?).  I haven't been able to determine exactly why though*.
In most cases it's randomly generated afaict.

I'd consider using it to replace whoopsie-id which is generated from
the machines BIOS information now to track bugs reported from the same
machine in the Ubuntu error tracker[1].   It would need to stay
constant for that install and be easy to get locally via file
collection which is why I think I'd prefer using the straight
machine-id to the just added app helper function[2].

Kind regards,
Bryan

* My best theory is it might show randomness bugs near the time of ssh
key generation, but then you have bigger problems.
