I think kvm grovelling should have been expunged years ago, so I'm not
going to protest in the least.
For debugging, I think what's wanted is one tool that reads the
complete sysctl/kernfs/*ctl/whatnot tree from a crash dump, and set up
tools like netstat to be able to read from that. Or maybe even create
a wedge in the libc sysctl interface for it. This would allow almost
anything that can be done now, only more reliably.
In the long term it may even be possible to generate much of the
extraction tool automatically based on sysctl node definitions,
although that will probably take some work.
