* Don't install daemontools.Guilhem Moulin2015-06-071

* Replace IPSec tunnels by app-level ephemeral TLS sessions.Guilhem Moulin2015-06-071
| | | | | For some reason giraff doesn't like IPSec. App-level TLS sessions are less efficient, but thanks to ansible it still scales well.
* Make genkeypair.sh able to display TXT record for DKIM signatures.Guilhem Moulin2015-06-071

* Don't require a PKI for IPSec.Guilhem Moulin2015-06-071
| | | | | | | | | | | Instead, generate a server certificate for each host (on the machine itself). Then fetch all these certs locally, and copy them over to each IPSec peer. That requires more certs to be stored on each machines (n vs 2), but it can be done automatically, and is easier to deploy. Note: When adding a new machine to the inventory, one needs to run the playbook on that machine (to generate the cert and fetch it locally) first, then on all other machines.

* Configure NTP.Guilhem Moulin2015-06-071
