Copy /kernel to different name, say kernela, and then recompile kernel source containing changes and it will replace /kernel, then copy /kernel to different name, say kernelb. When you want to return kernela copy kernela to kernel and reboot. You will have to change the flag on /kernel before you can overwrite it. Use commands like this chflags noschg /kernel cp /kernela /kernel chflags schg /kernel -----Original Message----- From: owner-freebsd-questions@freebsd.org [mailto:owner-freebsd-questions@freebsd.org]On Behalf Of Fernan Aguero Sent: Wednesday, May 28, 2003 10:58 AM To: questions@freebsd.org Subject: booting a different kernel each time Hi, I need to send my everyday machine (pentiumIII) to repair. I will take the disks and move them to a spare pentiumI so I can keep working meanwhile. The problem is I need to have a kernel that will work with a different processor and with a different ethernet card. My question: are there any issues in having two different kernels and booting from the alternatively? I mean switching kernels before booting so I don't have to 'unload' a kernel at boot time and then load a diffent one. And: should I backup both the kernel and the kernel modules under a different name (kernel.p3, modules.p3/) so I can then boot from it later?
