Code review comment for ~paelzer/ubuntu/+source/chrony:merge-cosmic-3.3-1

Note: did some more tests and so far all worked fine

Note (to myself): there is an interesting discussion in regard to RNG usage conflicting with newer kernels (4.17). The discussion is atm ongoing on the kernel side and might sort out there. If not there will be a 3.3.1 release with a fallback to urandom and being non-blocking.
TL;DR: no change due to that ... yet
