- (Array<String>) GetReadyCDs
Return list of ready CD devices for installation. It works properly only in the first installation stage - it reads content of /etc/install.inf file. It returns the installation (boot) CD device if it's known or it probes for all CD devices and returns ready devices (the devices which contain a medium). If repository is not CD/DVD it returns empty list.
