Hi intrigeri,

just ran tails again to stop the time it takes. Now it was instantly off (like 2 seconds or so).
I think it was a different bug I had before. The output looked like some systemd shutdown messages but they ran by too fast to read.

Anyway, with this cleared there's no need anymore for my idea with logging the addresses.

I'm sry for robbing you of your precious time.

How long does it take for you?

We would need to log all memory addresses that have ever been used
during a Tails session. Does the Linux kernel provide ways to do so
without impacting performance too much?
