When updating CentOS 7.0 from any kernel to latest 3.10.0-123.6.3, multiple UEFI or EFI BIOS boot entries are created. The entries are unknown to the user, until further looking into BIOS boot options. Each cold boot of a machine recreates a duplicate set of BIOS boot options, thus duplicating enteries until MAX (99). The PC acts as normal, yet creates new UEFI or EFI enteries multiple times over.
