We're drafting a proposal for a generic snapshot boot mechanism, to allow booting into previous snapshots of the system for LVM2 and BTRFS volumes (as well as Stratis[1] in the future). The current version of the design is available on GitHub (as a PDF or LyX source): https://github.com/bmr-cymru/snapshot-boot-docs This documents the current state of support for booting into snapshot volumes, as well as a brief survey of some of the current competitive implementations, and proposes new software components to facilitate easier use of the facility and additional functionality that can be provided once basic infrastructure is available. The document is still under active development and new revisions will be issued as feedback is received and integrated: we'll review the work as we go and decide on a final implementation.
