Hi,

I am trying to understand the inner working of klik2 by running strace.

I want to trace how the klik works, but when trying to check its forks,
its error out.  

Using strace klik path_to_app, it works and the app, xvier, would start.

Using strace -f klik path_to_app, it errors out saying that error
mounting the image file, where it is trying to run fuseiso.

Using sudo strace -f klik path_to_app, it errors out saying that klik
does not run as root.

Any idea how to properly trace the fork of klik? 

Thank you!
