Change core file names in Sandbox

[Amanda Moran]

When creating a sandbox we should change the name of core files so that users will not have to do it themselves.

echo "/tmp/cores/core.%e.%p.%h.%t" > /proc/sys/kernel/core_pattern

I would suggest using the following pattern

/tmp/cores/core.%t.%h.%p.%e

i.e. core.<timestamp>.<hostname>.<pid>.<program> or core.12345678.host.1234.tm which will produce a list of core files with the ls command automatically sorted by timestamp which is more important than being sorted by the program name.
