Comment 14 for bug 1784132

As I indicated above, without running it it looks very much like the script will break on non-Debian systems. Developing the script to run on all supported platforms (now including CentOS 7.5) takes time, but it needs to be done. If you are unable to do this by using VirtualBox or another hypervisor, then I'll need to do it, which means incorporating the enhancement into a release will not occur until after several months.
