@p @Economic_Hitman if i'm not mistaken the whole "re-generate machine-id every boot" thing started when tails introduced a unit to rm the machine-id file every shutdown, and since tails did that and recommend doing that, then many started following suit, some even make up reasons why static machine-id is a bad thing that were never stated by tails, in tails the forefront practical reason is that a tails pendrive may be used on different hardware every boot so a static machine-id makes no sense there, the second forefront reason has to do with the "amnesiac" part of tails ensuring it never remembers which hardware was last booted into.
