We’ll assume your Fossil repository stores something called
“`myproject`” within `~/museum/myproject/repo.fossil`, named according
to the reasons given [above](#repo-inside). We’ll make consistent use of
this naming scheme in the examples below so that you will be able to
replace the “`myproject`” element of the various file and path names.

If you use [the stock `Dockerfile`](/file/dockerfile) to generate your
base image, `nspawn` won’t recognize it as containing an OS unless you
put a line like this into the first stage:
The first configuration step is to convert the Docker container into
a “machine,” as `systemd` calls it.  The easiest method is:

```
COPY containers/os-release /etc/os-release
```

That will let you produce a `systemd` “machine” via the OCI image:

```
  $ make container
  $ docker container export $(make container-version) |
    machinectl import-tar - myproject
```

Next, create `/etc/systemd/nspawn/myproject.nspawn`, containing
Next, create `/etc/systemd/nspawn/myproject.nspawn`:
something like:
