Odd things Ubuntu does
Having just booted a new VM up using the official #Canonical #Ubuntu image on #Azure, I noticed that, during the first boot cycle, it makes a call out to "entropy.ubuntu.com"
This is done by the "polliniate" package which describes itself:
pollinate is an entropy as a service client. It will fetch a random seed from one or more remote servers, and feed those into a (pseudo) random number generator. This is often useful in cloud and virtual machine environments with limited sources of entropy.
https://manpages.ubuntu.com/manpages/jammy/man1/pollinate.1.html
There's something oddly jarring about this. Not least because this call-out for "supplementary" entropy is done after generating the host's SSH keys.
I hope, hope very much, that someone with Prof in their title from a very well regarded Computer Science department has written a paper suggesting this is ok.
