thanks for writing the howto

[Dave Morgan]

I followed the new howto, and managed to get nts.morgad.co.uk running
(rasbian Jessy - headless, text terminal only)

Installing certbot-auto was a bit buttock-clenching, as I waiting for 
pip to install stuff - no screen updates for 5 min or so, it felt like 
forever :)

It seems to like ntp2.glypnod.com a lot more than the other servers.
