Some users report munin is broken because munin and munin-node disagree about the name of the machine. I think this occurs if hostname (used by munin-node) reports a different name than PRIMARY_HOSTNAME (which we put in the munin config).
Hard-code PRIMARY_HOSTNAME in munin-node.conf.
Fixes#474.

--------------------
This is a minor update to v0.11, which was a major update. Please read v0.11's advisories.
* The administrator@ alias was incorrectly created starting with v0.11. If your first install was v0.11, check that the administrator@ alias forwards mail to you.
* Intrusion detection rules (fail2ban) are relaxed (i.e. less is blocked).
* SSL certificates could not be installed for the new automatic 'www.' redirect domains.
* PHP's default character encoding is changed from no default to UTF8. The effect of this change is unclear but should prevent possible future text conversion issues.
* User-installed SSL private keys in the BEGIN PRIVATE KEY format were not accepted.
* SSL certificates with SAN domains with IDNA encoding were broken in v0.11.
* Some IDNA functionality was using IDNA 2003 rather than IDNA 2008.
---------------------
Advisories:
* Users can no longer spoof arbitrary email addresses in outbound mail. When sending mail, the email address configured in your mail client must match the SMTP login username being used, or the email address must be an alias with the SMTP login username listed as one of the alias's targets.
* This update replaces your DKIM signing key with a stronger key. Because of DNS caching/propagation, mail sent within a few hours after this update could be marked as spam by recipients. If you use External DNS, you will need to update your DNS records.
* The box will now install software from a new Mail-in-a-Box PPA on Launchpad.net, where we are distributing two of our own packages: a patched postgrey and dovecot-lucene.
Mail:
* Greylisting will now let some reputable senders pass through immediately.
* Searching mail (via IMAP) will now be much faster using the dovecot lucene full text search plugin.
* Users can no longer spoof arbitrary email addresses in outbound mail (see above).
* Fix for deleting admin@ and postmaster@ addresses.
* Roundcube is updated to version 1.1.2, plugins updated.
* Exchange/ActiveSync autoconfiguration was not working on all devices (e.g. iPhone) because of a case-sensitive URL.
* The DKIM signing key has been increased to 2048 bits, from 1024, replacing the existing key.
Web:
* 'www' subdomains now automatically redirect to their parent domain (but you'll need to install an SSL certificate).
* OCSP no longer uses Google Public DNS.
* The installed PHP version is no longer exposed through HTTP response headers, for better security.
DNS:
* Default IPv6 AAAA records were missing since version 0.09.
Control panel:
* Resetting a user's password now forces them to log in again everywhere.
* Status checks were not working if an ssh server was not installed.
* SSL certificate validation now uses the Python cryptography module in some places where openssl was used.
* There is a new tab to show the installed version of Mail-in-a-Box and to fetch the latest released version.
System:
* The munin system monitoring tool is now installed and accessible at /admin/munin.
* ownCloud updated to version 8.0.4. The ownCloud installation step now is reslient to download problems. The ownCloud configuration file is now stored in STORAGE_ROOT to fix loss of data when moving STORAGE_ROOT to a new machine.
* The setup scripts now run `apt-get update` prior to installing anything to ensure the apt database is in sync with the packages actually available.
* Add a migration to delete any existing DKIM key so that existing machines get a fresh 2048-bit key. (Sadly we don't support key rotation so the change is immediate.)
* Because the DNS record for a 2048-bit key is so much longer, the way we read OpenDKIM's DNS record text file had to be modified to combine an arbitrary number of TXT record quoted ("...") strings.
* When writing out the TXT record value, the string must be split into quoted ("...") strings with a maximum length of 255 bytes each, per the DNS spec.
* Added a changelog entry.
* Use `cryptography` instead of parsing openssl's output.
* When checking if we can reuse the primary domain certificate or a www-parent-domain certificate for a domain, avoid shelling out to openssl entirely.
* Set ssl_stapling_verify to off per https://sslmate.com/blog/post/ocsp_stapling_in_apache_and_nginx ('on' has no security benefits).
* Set resolver to 127.0.0.1, instead of Google Public DNS, because we might as well use our local nameserver anyway.
* Remove the commented line which per the link above would never be necessary anyway.
OCSP seems to work just fine after these changes.
* Split the nginx templates again so we have just the part needed to make a domain do a redirect separate from the rest.
* Add server blocks to the nginx config for these domains.
* List these domains in the SSL certificate install admin panel.
* Generate default 'www' records just for domains we provide default redirects for.
Fixes#321.
* SMTP Submission (port 587) began offering the insecure SSLv3 protocol due to a misconfiguration in the previous version.
* Roundcube now allows persistent logins using Roundcube-Persistent-Login-Plugin.
* ownCloud is updated to version 8.0.3.
* SPF records for non-mail domains were tightened.
* The minimum greylisting delay has been reduced from 5 minutes to 3 minutes.
* Users and aliases weren't working if they were entered with any uppercase letters. Now only lowercase is allowed.
* After installing an SSL certificate from the control panel, the page wasn't being refreshed.
* Backups broke if the box's hostname was changed after installation.
* Dotfiles (i.e. .svn) stored in ownCloud Files were not accessible from ownCloud's mobile/desktop clients.
* Fix broken install on OVH VPS's.
