+
+Transactional, in-place operating system updates using OCI/Docker container images.
+
+The original Docker container model of using "layers" to model
+applications has been extremely successful.  This project
+aims to apply the same technique for bootable host systems - using
+standard OCI/Docker containers as a transport and delivery format
+for base operating system updates.
+
+The container image includes a Linux kernel (in e.g. `/usr/lib/modules`),
+which is used to boot.  At runtime on a target system, the base userspace is
+*not* itself running in a container by default.  For example, assuming
+systemd is in use, systemd acts as pid1 as usual - there's no "outer" process.
