nowadays with multicore systems widely available it would be very nice to have a system-wide configuration option somewhere - like rc.conf, or security/limits.conf -, which is taken into account by the start-stop-daemon within each initscript, that allows pinning of the started process to a given cpu using the taskset command

There is a kernel part and a userland part. Try out the tools installed with dev-libs/libcgroup, perhaps? Newer sys-apps/openrc has support for cgroups already. Is there anything special you are looking for here?

(Continuing my bug). I didn't use cgroups, I quickly read documentation so it's high chance I'm wrong. Meseems it's a little problematic to put a few very similar tasks (like two redis instances or qemu VM running as the same user 'nobody') to diffrent cgroups. It's possible to put task usnig pid (what about threading apps?) but it looks openrc doesn't have such funcionality (yet?).
