The casync filesystem image distribution tool

Lennart Poettering announcescasync, a tool for distributing system images."casync takes inspiration from the popular rsync file synchronizationtool as well as the probably even more popular git revision controlsystem. It combines the idea of the rsync algorithm with the idea ofgit-style content-addressable file systems, and creates a new system forefficiently storing and delivering file system images, optimized forhigh-frequency update cycles over the Internet. Its current focus is ondelivering IoT, container, VM, application, portable service or OS images,but I hope to extend it later in a generic fashion to become useful forbackups and home directory synchronization as well."
