### What needs to get done Snapcraft should add a deprecation notice if the `snap_daemon` system username is used. ```yaml system-usernames: snap_daemon: shared ``` ```bash Warning: The system username 'snap_daemon' is deprecated. See https://snapcraft.io/docs/system-usernames. ``` ### Why it needs to get done Because snapd has deprecated the username. See https://snapcraft.io/docs/system-usernames.
