Hi, are there any tutorials / packages out there that address the situation of patching / upgrading / changing the installed kernel remotely?
three main problems come to my mind that could bring a fatal situation of not being able to access the machine after a reboot: A kernel does not work with hardware for any reason and machine hangs B kernel / modules do not work with network device for any reason. C kernel does not start sshd for any reason How would one prevent this? is it possible to reboot old kernel automatically A if system boot does not finish properly B if modules for net-devices are missing / not working C if the new one does not start all services (esp. sshd) Are there any solutions to this out there? B + C could be resolved with some kind of script, I guess, but A seems to be impossible to be done remotely? How do i change back lilo.conf, if I have no ssh.login to the machine? I was looking for a "boot kernel-new only once, next time boot old kernel", that could help, but I did not found this? Any ideas? Thank you very much for your attention! Have a nice thread, Peter
