Hi, i have the absolut identical file for Windows which works as
expected (logging), but not for linux:

There is just no logging - i started everything as root. Even when i
use the FileAppender with its file name property set to "somelog.log"
or "/root/somelog.log" it just saves nothing and i have no idea why.

I used updatedb && locate to find a file called like this but there
was nothing. Also lsof with a grep find nothing opened. So it is
really not logging.

Your config for the RollingFileAppender is missing the <file> element. The manual contains a good example of all the necessary elements [1]. logback should print a warning in the debug output for this.

It would be helpful if you provided additional details to reproduce the problem:

 * What version of logback and slf4j are you using?
 * Which flavor (and version) of Linux are you running? 
 * Does the same problem occur when you try your logback config in a simple HelloWorld app (outside of install4j)?

FYI, your logback config works (writes to a file) for me in Android.

It looks like Install4j supports a console [2], when running  the installer with "-c". It might be worth seeing if logback's debug-output prints in that console.
