Today's master has some major changes to the /boot structure:
* Kernels and modules are no longer installed in /boot/kernel and
/boot/modules. Instead /boot/kernel is a directory and the kernel
and modules are installed in that directory, similar to FreeBSD.
This allows us to multi-boot different kernels each with their
own set of modules, avoiding problems when old modules become
incompatible with new kernels.
In addition a loader.conf may be placed in each directory for
localization... for example, allowing a different root volume
to be specified and thus making it possible to boot a 32 or 64 bit
kernel via the menu system.
* The FICL 4th loader/menu has been ripped out. Making it work
properly with the new directory structure exceeded my maximum
I wrote a new menu system in C from scratch called dloader. It's
basically a new frontend to the boot/common code that is already
supporting the boot system. We can expand it as needed.
* The installkernel target will refuse to install if you have not
updated your /boot via a build/installworld or a recompilation
and install of /usr/src/sys/boot (be sure to make clean before
recompiling it!). This is because the old boot loader will get
rather confused from the new directory structure.
