    - asserts,overlord/assertstate: introduce an assertstate task
      handler to fetch snap assertions
    - spread: disable re-exec to always test development tree.
    - interfaces: implement a fuse interface
    - interfaces/hardware-observe.go: re-add /run/udev/data
    - overlord/assertstate,daemon: reorg how the assert manager exposes

    - asserts: export DecodePublicKey
    - asserts: introduce support for assertions with no authority,
