froller at metis:~$ locate lib/udev/devices/core
/lib/udev/devices/core
froller at 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 at 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.
