Hello, I'm trying to get unprivileged Subhurds to work. The first part of the puzzle is in fact a tiny kernel patch to provide a robust parental relationship of tasks to userspace. Currently, /hurd/proc relies on posixesque processes to call proc_child to form a process hierarchy.
I've written about these notifications back in my gsoc days: http://lists.gnu.org/archive/html/bug-hurd/2013-09/msg00170.html I've got a patched up proc server and a boot program that do boot a non-privileged Subhurd. It actually bootstraps the core Hurd servers, and starts `runsystem', but then the Subhurds proc server crashes. Overall it's looking good, time to get the discussion going. Cheers, Justus
