tl;dr:
load a new kernel in preparation for execution
basically just like a reboot from what i can tell. the more interesting option is the KEXEC_ON_CRASH flag. that seems pretty cool! i guess the idea would be to use it to either save critical data, or else dump a bunch of debug logs on panic. i wonder if there are any off the shelf images that are intended for use like this? or would one have to create their own bespoke software?
