Actually , a Kernel Selection menu in front of the Boot Loader menu is a more flexible method : First select kernel , then select its booting structure with the above described Boot Loader menu . My opinion is that , they should NOT be COMBINED into one single menu , because , in the same system , even there may be other kernels to be booted . Some operating systems , such as OpenSolaris and Mandriva Linux , after updating the kernel , they are keeping previous kernel in the Kernel Selection menu , under the new kernel name item . Such a system may be employed for the FreeBSD : If a kernel.old is generated , it may be inserted into Kernel Selection menu automatically . If , at present , there is no kernel selection menu but boot sector is used directly , kernel build system may modify that structure also to utilize a Kernel Selection menu . Thank you very much .
