ID: 7082 Title: Fixed "omd create" when fstab has 0 bytes Component: Site Management Level: 1 Class: Bug fix Version: 1.6.0i1 The "omd create" command failed with a "IndexError: string index out of range" in case a /etc/fstab file existed but was empty. While regular systems most likely have entries in there, this can often happen for containers.
