kdump operates by booting a fresh kernel to capture the context of a crashed kernel, and so the only way for kdump to dump a kernel is to crash it and cause kdump to invoke its post-crash kernel. You can manually force a running kernel to panic (and invoke a correctly-configured kdump) with the following command sequence: > echo 1 > /proc/sys/kernel/sysrq > echo c >

I'm sure most people here know about Dash in Debian. Have there been discussions about providing a more efficient shell in Centos for use with heavily invoked non-interactive scripts? With sh being a link to bash in Centos I don't know if it would explode if the link was changed to something else, but at least the scripts we made on our own that run certain services could be changed and

Kubernetes isn't really a general-purpose UNIX operating system and so the question seems like it's comparing apples with oranges, at least, unless you're doing a very narrow and specific thing with certain automation and scalability requirements. I don't think the fundamental raison d'?tre for a UNIX workstation or server operating environment has changed in four decades,
