Comment 1 for bug 1857019

FWIW, this is probably a low priority bug since as per pedronis, the correct snapcraft.yaml for the snapd snap is (appreviated):

```
type: snapd
build-base: core
```

however we're not yet to the point where the store supports `type: snapd` for the snapd snap yet, so while it would be useful to be able to specify `build-base: core` without `type: snapd` in the meantime, building with both `type: snapd` and `build-base: core` is a "workaround" for this bug (even if we really can't do that since the store is confused).
