Does UC also do this?

The post at the bottom is my question:

Chrome can and does look for this GUID when it launches...
https://askubuntu.com/questions/1149983/cant-symlink-to-machine-id
You can remove it:
/bin/rm -f /etc/machine-id
and regenerate it:
/usr/bin/systemd-machine-id-setup
at shutdown with a script.
The only issue I have noticed is that some applications like media players[Clementine] that are looking for sound devices don't appreciate the new ID right away. You may have to manually select the proper sound device before playing media.

I'm betting if it looks for it, it also stores it, which will be an attack vector later if Chrome decides to use it for something (or if it already is).

I just thought you might have missed this in the long run since it is an easy thing to miss, and you might want to know about it.

Thanks.
