Introducing Storage Instantiation Daemon
summary
Storage Instantiation Daemon (SID) provides a single service that identifies, groups and activates stacked storage layers, replacing complex udev rule hacks with a key/value database, snapshot view and staged processing. It uses an udev builtin to call SID on kernel uevents (kernel 4.13 adds richer keys), implements stage A (identify/scan/schedule) and stores persistent and delta-synced vector values, and already includes a multipath module; Storage Instantiation Daemon stage B (delayed activation and timeouts) remains under development on GitHub.
