The issue was that the old method simply didn't work. When the hosts
file should look like:
127.0.1.1 host.fqdn.com host
It looked like:
127.0.1.1 host.fqdn.com host old.fqdn.com old
Or this if the user didn't set a fqdn
127.0.1.1 host host old.fqdn.com old
This patch fixes that.
On Debian and Ubuntu guests, when the new hostname of the guest box is
set, the DHCP client (isc-dhcp-client) won't renew its DHCP lease with
the new hostname. Executing "ifdown -a; ifup -a" to reinitialize all auto
interfaces fixes this issue.
Furthermore, as vagrant will now actually wait until a DHCP lease is
acquired, it is guaranteed that the the correct domainname is set from
DHCP before calling other provisioners like puppet, that rely on it.
This fixes puppet/facter sometimes failing to find the fqdn fact on an
LXC guest when the DHCP server is responding too slow.
When dealing with lxc containers, '/proc/version' will have information
about the host machine kernel that can possibly have information about
an Ubuntu / Debian host, messing up with guest container detection.
On Debian systems config.hostname directive should change /etc/mailname
in order to prevent problems with default mailer trying to contact
default vm's name.
I don't use `activated` here because I'd really like to optimize
performance as much as possible, and loading files from disk is
generally slow. So instead of using `activated` I load the file at the
last possible moment which is when the exact class is being requested.
I don't think many people will do this outside of the core, and I'm not
too concerned.
