savecore

[mike at BRL.ARPA]

Alas, the BSD SAVECORE program has nothing to do with normal "core"
files that the kernel writes for you.  Thus, altering the coredumplimit
on your root shell is unrelated.  SAVECORE is a program run
by /etc/rc or /etc/rc.local at reboot time, to copy the crash dump
from swap space (eg, hp0b) into a normal UNIX file in /dirname/crash
(where dirname is the first arg to savecore).

The file dirname/minfree indicates how much space the filesystem
must have for savecore to start, to keep a sick machine from filling
the disk with kernel core dumps.
