Because we are not yet using the image store, this requires a
patched `ctr` that can run a specified rootfs rather than an
image.
We will switch to the image store later, but this requires
extensive build changes.

Instead of mounting a new filesystem, revert to doing a `rw` bind.
However do not make `/` `rshared`, just `/var` as that is where we expect
filesystems to be mounted for persistence. Also only make the actual
container rootfs writeable, not the whole directory.

As suggested by @shykes these are clearer
- onboot for things that are run at boot time to completion
- services for persistent services
