Hi Cyril, all,

Ah, sorry (editor macro when creating new file, I forget to delete it).

Do you mean to avoid this change:

-	tst_run_shell $(basename "$0") "$@"
+	tst_run_shell tst_exec.sh $(basename "$0") "$@"

and put the content here? I'll try it during this week.

+1. I figured this later after doing more debugging (preparation for internal
SUSE talk).

Thanks for your review!
