Kexec is the command > I wanted. ksplice and kexec are both ways to replace one running kernel with another running kernel without a full reboot and with continuous uptime. ksplice is older and has now been emborged by Oracle, Inc. -- which, come to think of it, may have inspired the development of kexec as an alternative approach. ___ vox-tech mailing list vox-tech@lists.lugod.org http://lists.lugod.org/mailman/listinfo/vox-tech

[vox-tech] replace running kernel with new one
Hello, Before my friend Hugh Daniels passed away he mention there was a way to fork/exec/chain a new kernel to replace the current running kernel. Due to his passing, I never did learn how. The plan was to have a small OS on either a USB flash drive, or an SSD. Once it was up and running, it would then replace the current kernel with the one on the hard drive. This way you could ssh into the system and work on it (much like having the system in a VM but not doing so). This method would allow you to do low level work on the system (run a FSCK, or fix a RAID and so on). Does anyone understand how to do this? Hugh said it would be much like a 'chain' command from Fortran. Tony ___ vox-tech mailing list vox-tech@lists.lugod.org http://lists.lugod.org/mailman/listinfo/vox-tech
