Comment 11 for bug 1108082

I wanted to rule out upstart or our procps settings (which incur some security restrictions); even if I boot with init=/bin/bash, all processes (including pid 1) has a coredump_filter of 23. So it seems this is really a kernel configuration issue. I think this is CONFIG_CORE_DUMP_DEFAULT_ELF_HEADERS option, which we don't set by default: http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/fs/Kconfig.binfmt#n46
