per-process coreadm would be useful
Similarly to #11530, I've wanted a way to make certain commands, or processes trees, not dump core or dump core differently.
I think we could do this via a couple of things.
coreadm ... -c cmd
In the same way as pid, but operating on a specified command which we execute.
And making more of the coreadm configuration per-process (currently, only the path and content of local dumps is in the proc_t).
After which one could do
% coreadm -d global,process -c ./testsuite
