you can also set "KERNEL" in the make and it will install to
/boot/$KERNEL/
It would need to put the symbols in /usr/lib/...$KERNEL/ as well, and
then you are bound to get confusion when you copy the new kernel to
the default place when you tested it. maybe put a symlink in the
kernel directory and follow that? keeping symbols and kernel in sync
is going to get a lot more complicated.
