The /proc/PID/coredump_filter mechanism makes it easy to tweak the
per-process setting to control ELF core dump style details.
This setting is per-process (per-mm) and inherited by children.
But as a user, the /proc interface is insane. It prints a magical hex
value (without a leading 0x, to make it sneaky), which you'll be damn lucky
to figure out from reading Documentation/filesystems/proc.txt. Then you
get to set it to another such magical value, which is in decimal unless you
add a leading 0x (cat /proc/x/coredump_filter > /proc/y/coredump_filter
does not copy the setting, go team).
I have kicking around this half-assed bash script that I don't care to
bother making really presentable. Where should it live? In the upstream
kernel's scripts/? (Then noone would ever see it for sure.)
In util-linux-ng? Or what? Someone want to take it off my hands?
either util-linux or procps is my suggestion.
