The list is controlled by the /boot/loader.conf variable kernels=
which defaults to "kernel kernel.old"

I have a patch almost ready to land that will search all subdirectories
of /boot for a file named 'kernel' and add the names of those
directories to the list, such that the list will basically be autogenerated.

It currently contains too much copy/pasted code, and I just need to
clean it up a bit:

It was originally designed as part of my contributions towards packaged
base, where pkg will keep the last N (default to 5 I think) kernel
packages you have installed around, incase an upgrade goes bad.

This feature will work on any filesystem supported by the loader.
