Hi, all, This is my first post to the list and I'm new to kexec. I'm wondering if it's possible to persist a ramdisk across a kexec 'reboot'. In the normal reboot case, this isn't possible as the BIOS may do who-knows-what to memory, but if I understand correctly, this isn't a problem in the kexec case. I'd imagine there would have to be a certain memory marker or a kernel command line option so that the new kernel could find the ramdisk. I figured this might exist already, but I probably don't know enough to find what I'm looking for. The use case here is booting from a LiveCD, fetching a more-current kernel and tools off the Internet, and then booting into it. I'm not really sure if having the kernel on the ramdisk makes it harder or not (it would still be worthwhile for non-kernel data). Some of the kboot docs make me think it could be possible, but I don't understand the hand-off mechanism for resources handled by the previous kernel. If anybody knows if this is doable please point me in the right direction, or to docs I ought to be reading to better understand the mechanics.
