The current command "service <package-name> start" does not apply to RHEL-6; the service name ("qemu-ga") differs from the package name ("qemu-guest-agent") there. Overhaul the logic -- detach the command from the package name; cover the RHEL, ALT, SUSE and Debian families separately. Remove the "chkconfig" command, as in all tested / investigated cases, it is unnecessary.
