It should be possible without any significant side effects apart from generating cores
and traces. But to enable this, I believe, it would need alteration to the default system
Would it be possible? What is the package providing the default env vars?
systemd has DefaultEnvironment= in /etc/systemd/system.conf, but it is
supposed to be used to create local overrides, and doesn't work well
for this case (it's %config(noreplace) among other problems). In general
setting global env vars does not work.
Instead, it would be nicer to modify the go runtime to default to a coredump
if GOTRACEBACK= is not set. This would cover more cases and would not pollute
the environment for users who are not using go.
