I've noticed that my system has a delay during boot-up, of about
20secs. It
*looks* like NM is waiting for urandom - there's no " NetworkManager
(version 1.8.2) is starting " message until right after "random:
pool is initialized ".
That might just be a coincidence (though other services etc *have*
by then), but if not then I'm curious what the dependency is (and
there's a way round it for faster boot).


that is quite possible that NM reads urandom.
For example, to generate a key in /var/lib/NetworkManager/secret_key

That doesn't seem wrong.

We could try to call getrandom() instead, but that probably would block
just as long.


Thanks Thomas. I found your blog related to this - - 
is the use of urandom only related to WiFi and/or IPv6 functionality (which I don't need), and could it be 
disabled with a config setting?
