It seems strange that I need to be root in order to say "place cores in my current directory" (via
cat whatever /proc/sys/kernel/core_pattern). Isn't there any user-specific override for this?
On my node:
ll /proc/sys/kernel/core_pattern -rw-r--r-- 1 root root 0 Mar 1 21:32 /proc/sys/kernel/core_pattern
It is only writable by root.
chmod 666 /proc/sys/kernel/core_pattern chmod: changing permissions of `/proc/sys/kernel/core_pattern': Operation not permitted
So I think you may not be able to override it.
