Sure. This is merely meant to be a meta-name for the kernel that has panicked. In your case, it seems it's actually really /kernel still. Note that if you're enabling crash dump recording in /etc/rc.conf (dumpdev="/dev/wd0s1b" in your case), the rc scripts handle the default savecore case (i. e. saving a core dump for the kernel that has been booted again) by default, so you don't need to type it manually in single-user mode as above. The instructions using the name "kernel.panicked" have been written with the idea in mind that your new kernel panics right away when booting. In that case, it's often only possible to boot an alternate kernel (like kernel.old). That however means that the default savecore logic wouldn't work (since it would try to save a coredump for /kernel.old, but the coredump has actually been made from /kernel, again the names are /examples/ only), so you would have to type it manually. Maybe someone from doc@freebsd.org can clarify the wording a little. -- cheers, J"org .-.-. --... ...-- -.. .
