​I added the option since we discovered that the entropy pool can take a
very long time to fill, and while this generally doesn't affect startup
(sshd etc. are usually started on demand) it may be problematic for
services like kerberos, an SSL enabled web server.

It's largely irrelevant for the basic OS components, though.
