How about: The new kernel and modules will be copied to the /boot/kernel directory. I= f=20 the currently running kernel came from "/boot/kernel", then the old kernel= =20 and modules will be moved to the /boot/kernel.old directory. > -- In section 8.6, under "The kernel does not boot", > > change > You cannot rely on > kernel.old because when installing a new kernel, > kernel.old is overwritten with the last installed kernel > which may be non-functional. > to > Standard kernel builds write to /boot/kernel, with > that directory first moved in place of /boot/kernel.old > if the currently running kernel came from /boot/kernel. I haven't read the full doc for context, but it looks like the replacement= =20 text doesn't actually replace the same meaning. The reason for kernel.old= =20 only getting updated if the kernel being installed is running is to try to= =20 make kernel.old more reliable as in theory it should always be a kernel tha= t=20 was running well enough to do an installkernel now. Probably the surroundi= ng=20 section here needs more updating to reflect that larger change. =2D-=20 John Baldwin <jhb@FreeBSD.org> =A0<>< =A0http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" =A0=3D =A0http://www.FreeBSD.org
