- Ensure that /var/lib/private/shadowsocks-libev/freedombox always exists. This fixes not being able to save configuration after setup on fresh Buster installs. - Merge migration path from version 1 to 2 into setup process in an idempotent way. - Always creating an initial configuration file so that daemon starts soon after install. Set a default random password. Localhost as default server. Closes: #1792 Signed-off-by: Nektarios Katakis <iam@nektarioskatakis.xyz> [sunil: Minor indentation, update commit message] Reviewed-by: Sunil Mohan Adapa <sunil@medhas.org>
