[I] Log service can't find ROOT logger and doesn't support variable substitution when using Logback logging backend [karaf]

["jbonofre (via GitHub)" <gi...@apache.org>]

jbonofre opened a new issue, #2147:
URL: https://github.com/apache/karaf/issues/2147

   When using logback as logging backend with custom distribution, Karaf fails to find the root logger.
   
   ```
   karaf@root()> log:get
   Logger │ Level
   ───────┼──────
   ```
   
   And when issuing `log:set DEBUG` it creates duplicate entry in `logback.xml`:
   
   ```
   <root level="WARN">
      <appender-ref ref="FILE"/>
      <appender-ref ref="OSGI"/>
   </root>
   <root level="DEBUG"/>
   ```
   
   Also it doesn't support variable substitution e.g.
   
   ```
   <logger name="test" level="${LOG_LEVEL:-WARN}"/>
   ```
