Read against hal/modules/mssql: the predecessor publishes 4848:1433 and its connections
block hands every consumer localhost:4848; its data has lived in /services/mssql/data
since it was installed — 4.6 GB of it. The nox module had 1433, db-data, and a pin three
builds behind, so taking it would have moved the port every consumer was told about,
started on an empty directory, and downgraded the engine at the same time.
db-data was not a convention: only this module and mongodb used it, and both predecessors
say data. Now nothing moves at the cutover.
