Inherited from the design of Nix, most of the content of the package manager is kept in a directory /gnu/store where only the Guix daemon has write-access. This is achieved via specialised bind mounts, where the Store as a file system is mounted read only, prohibiting interference even from the root user, while the Guix daemon remounts the Store as read/writable in its own private namespace.
Docker uses file systems inspired by Unionfs, such as Aufs, to layer Docker images. As actions are done to a base image, layers are created and documented, such that each layer fully describes how to recreate an action. This strategy enables Docker's lightweight images, as only layer updates need to be propagated (compared to full VMs, for ...

Josh Allen becomes a huge favorite. The -400 odds for Allen put him close to being a lock to win the award, in the eyes of oddsmakers. The implied odds for a -400 favorite is 80%.
The docker-compose CLI utility allows users to run commands on multiple containers at once; for example, building images, scaling containers, running containers that were stopped, and more. [31] Commands related to image manipulation, or user-interactive options, are not relevant in Docker Compose because they address one container. [32]
As in Plan 9, operations traverse this stack top-down to resolve names, but unlike Plan 9, BSD union mounts are recursive, so that the contents of subdirectories appear merged in the union directory. Also unlike the Plan 9 version, all layers except the top are read-only: modifying files in the union causes their contents to first be copied ...
