+# Role `sane_debian_system` – set up a manageable Debian system
+
+This role sets up a Debian system so that it can be managed with
+Ansible in a reasonable way.
+
+## Minimally sane Debian system
+
+~~~scenario
+given a host running Debian
+when I use role sane_debian_system
+and I use variables from sane1.yml
+and I run the playbook
+then the host has the sudo package installed
+and the host has the apt-transport-https package installed
+and the host has the locales package installed
+and the host has the ntp package installed
+and the host has an empty /etc/apt/sources.list.d directory
+~~~
+
+FIXME: this step doesn't work, since the role doesn't currently tell
+the kernel the new hostname.
+
+~~~
+and the host has hostname saneone
+~~~
+
+~~~{#sane1.yml .file .yaml}
+sane_debian_system_version: 0

+debian_codename: buster
+hostname: saneone
