X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 06 Oct 2003 12:11:36 -0000 Hi, I'm currently in the process of upgrading my kernel (5.1). Afaik, every time one installs a new kernel with "make installkernel" the old /boot/kernel is moved to /boot/kernel.old thus overwriting the old /boot/kernel.old. In order to keep a working kernel: Is it possible to *keep* an old kernel by copying, say /boot/kernel.old to e.g. /boot/mykernel and then via the boot-menu starting this kernel by unload boot mykernel ?? If yes, can I simply copy (e.g. via tar | tar xpf..) the old kernel directory to a new name or is there anything else I should consider? TIA for your help -ewald
