ClangBSD had little to no runtime testing, so you should be careful
with it. I'm not saying it won't work, but make sure you have backups
in case something goes wrong.

Also, if you just want to build the kernel, you don't need ClangBSD,
you can just install llvm-devel from ports and use

Some people ran or are running their systems with clang compiled kernel.
You should still be careful, and some things (like snd_hda on amd64)
are known to have problems.
