It is. Basically it is the normal kexec interface that allows you to boot another kernel. With a few restrictions that should keep it as reliable as possible when the kernel has not shut itself down cleanly. The hardest case is to do a useful system core dump. As that requires looking at what has gone before. For the rest if you can do it with a kernel and a initramfs you are in good shape. There seems to be a significant amount of interest in the full system core dump case so that is what the work is concentrating on.
