This command allows users to cheaply inject configuration files in the
initramfs stage without having to regenerate the whole initramfs (or
even a new OSTree commit). This will be useful for configuring services
involved in bringing up the root block device.
```
$ echo 'hello world' > /etc/foobar
$ rpm-ostree ex initramfs-etc --track /etc/foobar
Staging deployment... done
Run "systemctl reboot" to start a reboot
