Sorry, I don't care enough to add the feature. It doesn't seem like
it would be hard at all though.

Trying to avoid future conflict here... if anyone has AIX,
please try "ps -o '%p %c %d'" and report the results.
Also look for other possibly undocumented format options.
Perhaps %D would be a safe choice.
Also %S for a single-digit serial number. (or %H for "hash")

Oh, this would be great:
/proc/sys/kernel/usercore "core" Normal stuff
/proc/sys/kernel/rootcore "core" Daemons mostly
/proc/sys/kernel/suidcore "" Currently undumpable
I don't see why we don't just dump setuid cores with mode 000
and owner root, restricted to unix-like filesystems.

Give it a try if you want the feature. Kernel programming is no worse
than DOS programming. If you crash, hit the reset button.
