The configuration of bitwarden_rs is done through environment variables,
+
therefore the names are converted from camel case (e.g. disable2FARemember)
+
to upper case snake case (e.g. DISABLE_2FA_REMEMBER).
+
In this conversion digits (0-9) are handled just like upper case characters,
+
so foo2 would be converted to FOO_2.
+
Names already in this format remain unchanged, so FOO2 remains FOO2 if passed as such,
+
even though foo2 would have been converted to FOO_2.
+
This allows working around any potential future conflicting naming conventions.
+
+
Based on the attributes passed to this config option a environment file will be generated
+
that is passed to bitwarden_rs's systemd service.
+
+
The available configuration options can be found in
+
<link xlink:href="https://github.com/dani-garcia/bitwarden_rs/blob/1.8.0/.env.template">the environment template file</link>.
