+# Update packages on ubuntu and freebsd
+:microscope: #1
+
+The Vagrant file being used is a copy from
+`https://github.com/stationgroup/vagrant-labs/tree/master/imperialspeculate`.
+
+Two roles are being used: debian-upgrade (an upstream Galaxy role) and
+freebsd-upgrade (a small role based on what was proposed in the comments of #1
+and extended with proper support for check mode.)
+
+The upgrade process is contained in the playbook os_upgrade.yml, which will
+automatically create proper groups for Ubuntu and FreeBSD hosts. If unneeded,
+this first play can be left out, and the target hosts: in the second play can be
+replaced by the relevant groups you have in the inventory (e.g. ec2 tags.)
+
+A local ansible.cfg is defined, and needed for these scripts to run out of the
+box. This implies that all ansible commands must be run from the
+`ansible-experiments/package_updates` folder.
+
+A small script `setup-requirements` is provided, that initializes everything,
+to be executed after the vagrant boxes came online. It will generate an
+ssh-config for said vagrant boxes, download roles from galaxy, and make a
+base-install for the hosts (installing python dependencies, ansible itself
+on ubuntu1, a deploying an ssh key to all nodes to be used from the vagrant box
+`ubuntu1`, as ansible controller machine.)
+
+When deploying and setting up from the machine where vagrant runs, you need to
+add some extra arguments:
+`--ssh-extra-args "-F ./vagrant-ssh-config" --inventory hosts-vagrant`
+to ansible execution. These are not necessary once running ansible from
+`ubuntu1`.
+
+## BUGS
+
+The vagrant setup seems to have a provisioning bug, that kicks in with the
+latest 18.04 Ubuntu. The FreeBSD boxes also experience a provisioning problem,
+with the same result: the second, private network interface does not get
+configured. As these interfaces are used to run ansible from `ubuntu1`, I could
+not fully test the scripts from there.
