froller@metis:~$ locate lib/udev/devices/core
/lib/udev/devices/core
froller@metis:~$ whatis core
core (5) - core dump file

man core

NAME
core - core dump file

DESCRIPTION
The default action of certain signals is to cause a process to
terminate and produce a core dump file, a disk file containing an image
of the process’s memory at the time of termination. This image can
be used in a debugger (e.g., gdb(1)) to inspect the state of the
program at the time that it terminated. A list of the signals which
cause a process to dump core can be found in signal(7).
...

froller@metis:/lib/udev/devices$ ls -l
total 12
crw------- 1 root root 5, 1 2009-05-26 11:19 console
lrwxrwxrwx 1 root root 11 2009-05-26 11:19 core -> /proc/kcore

note that /lib/udev/devices/core links back to /proc/kcore and as I am
to understand it this happens when one of your systems or services
experiences a crash. Hope this helps and if anyone can expand on this
please do.

# rcS - runlevel compatibility

# This task runs the old sysv-rc startup scripts.

start on startup

stop on runlevel

# Note: there can be no previous runlevel here, if we have one it's bad

...

also, please end post as it makes it easier to keep up with the
conversation. Hope this helps.
