Hello List: I believe that the following issue was discussed in the past on this list, but I am unsure of its current status. Currently, (to my knowledge), one needs build a kernel, and in order to use this recently built kernel, one must reboot the computer. Wouldn't in be nice to have a system that once a kernel is built, implement the new kernel without a software or hardware reboot? And, if there were any run-time problems with the new kernel, the system would revert back to the previously runnable kernel..I can see some possible problems with swapping out a kernel and swapping in another within the same memory space in real-time, but has anyone investigated into possible solutions? I think that this would be a good project, if it could be done. Any system that currently comes to mind, needs a reboot in order to implement a kernel change, from Cisco to Linux. With systems that need to remain on ~24/7, a "hot-swappable" kernel would be a great solution to decreasing down-time. Just an idea. All suggestions, comments, and status are welcome. -Frank
