setup-sshd: prompt if root login should be enabled
Nowadays, OpenSSH's PermitRootLogin
option defaults to prohibit-password
thereby not allowing root login without a password by default. However, since setup-alpine does not configure any additional unprivileged user accounts you might end up with a system where you cannot login over SSH.
The OpenBSD installer resolves this by asking if root login should be enabled for OpenSSH or, alternatively, also allows configuring an unprivileged user account in the installer. IMHO setup-sshd should also prompt the user to check if root login should be enabled.
