[issue1140] installkernel POSTFIX directive

[Matthew Dillon]

    The problem I have is that having three different directives is, well,
    it is rather confusing.  I want to simplify it even more.

    I have an idea.  Please tell me if this is way off base.

    Why don't we just create a postfix out of the kernel name by default?
    So if you 'make installkernel KERNCONF=BLAH' you will get a
    /boot/kernel.BLAH and /boot/modules.BLAH ?

    So, for example, a GENERIC kernel would be installed as
    /boot/kernel.GENERIC and /boot/modules.GENERIC.

    We would then have a loader variable which defaults to 'GENERIC' in
    loader.conf, telling the loader which kernel to boot.

    How does that sound?
