I would like to use the GNU debugger (gdb) to trace hurd console (/bin/console) internals.
I've already patched gdb sources according to this previous post and I've successfully rebuilt the gdb package: now it works fine.
But I don't know how to run gdb and hurd console together (gdb uses the same console I try to trace into). Furthermore, the gdbserver package has not been ported to hurd, yet.
What is the technique to debug hurd console using gdb ?
