Having the "desktop" flavor of the kernel builds in use, apparently, I do: $ grep NUMA config/i386/desktop CONFIG_NUMA_IRQ_DESC=y # CONFIG_X86_NUMAQ is not set CONFIG_X86_SUMMIT_NUMA=y CONFIG_NUMA=y CONFIG_ACPI_NUMA=y > - where can I get the source files of your /sbin/init? http://download.opensuse.org/update/11.1/rpm/src/sysvinit-2.86-186.18.1.src.rpm but /sbin/init was just meant as an example. It happens for _all_ processes running from aufs branches.
