Discuss forking this into a kernel patch

[dagelf]

I've been dreaming of having a commandline in the kernel for a while. The current implementation with systemd should suffice though... but systemd might be too big for some embedded applications...

Then, having a modular way of adding more sysrq commands - and in fact, turning sysrq into a command line debugging interface that can run in stead of "halt" during a kernel panic, would be super useful. I am sure someone has done this, but I've not been able to find it...

Putting it into the kernel module (LKM) would be make it more robust, I think. Nice idea.

Especially now given the rising popularity of eBPF technology:
