Hello- Has anyone tried reconstituting a portion of the old kernel's /proc while in the capture kernel? I had the idea while digging through the kexec/kdump code and it seemed intriguing. It might be a means by which user-space dump applications running under the capture kernel could interrogate the old system, and identify bad processes that instigated the panic. In particular, I'm thinking of Out Of Memory scenarios. We've modified our kernel to panic instead of invoking the kernel's OOM killer, but we still have the problem of identifying the "bad" process while running in the capture kernel. Perhaps everything could be accomplished using some sort of FUSE file-system around /proc/oldmem and /proc/vmcore. Not all the proc/<pid>/ files would need to be implemented, of course. In addition, each old process could have its own 'vmcore' file for getting a core dump of the original process. What do you think? Am I tilting at windmills here?
