DESCRIPTION:In 2018 we introduced boom\, a tool that made snapshot booting 
 as simple as it should have been all along. Eight years later\, the questi
 on isn't "can I boot this snapshot?" but "which snapshots exist\, why did 
 I create them\, what changed\, and do I still need them?"\n\nEnter snapm: 
 a complete snapshot manager that handles everything from creation to sched
 uled garbage collection\, with plugins for LVM2 CoW\, LVM2 thin\, and Stra
 tis. Tell it what you want to snapshot\, and it figures out the fiddly bit
 s - no arcane incantations required.\n\nThis talk covers the journey from 
 boom's  beginnings to snapm's current capabilities: intelligent size polic
 ies\, multi-volume snapshot sets that actually work with systemd\, schedul
 ing with flexible retention policies (count\, age\, timeline)\, and the la
 test addition: the Difference Engine\, which answers "what actually change
 d?" with everything from JSON reports to fancy tree visualisations.\n\nLiv
 e demos included. Disasters may be simulated. Rollbacks will be swift.
