Can't you get your eBPF scripts into the BCC project? As far I can tell, the BCC
has been included in several distros already, and then it will become a part of
standard linux toolkits.

On the other hand, it seems many people are happy with the simple kernel OOM
report we have here. Not saying the current situation is perfect. On the top of
that, some people are using kdump, and some people have resource monitoring to
warn about potential memory overcommits before OOM kicks in etc.
