I would like to know why `"/data/mender/mender-store"` and `"/data/mender/mender-store-lock"` are required?

I couldn’t able to get more information on these files. 🤔

`/data/mender/mender-store` is a database where Mender stores information, e.g state.

`/data/mender/mender-store-lock` I assume this is created when database in use, to prevent multiple process to access it.
