### What needs to get done When rockcraft takes me into a `--debug` shell, it's not clear what went wrong and I end up poking in `../parts/` to see what's missing and where. It could be handy if the debug shell had a means to inform the user which part and step went wrong, for example: - PS1 envvar - Update and display `/etc/issue` ### Why it needs to get done Quicker troubleshooting.
