No, help-hurd is for questions from users, not developers.  Everything 
regarding the L4 port should be on this list, for the Mach port, there 
is debian-hurd for debian related things, and bug-hurd for the rest 
(except user questions).

From your original e-mail:

No.  The master control capability is not a universal thing, every 
capability can choose to either or not provide such a thing.  The root 
capability is built into the capability server (well, I think the patch 
I submitted[1] for that hasn't been applied yet, but it should be ;-) ). 
 It is the only way to access a capability server without having a 
capability for it.  I expect this functionality to be used mostly (if 
not only) for aquiring a capability from the server, with which further 
RPCs can be done.  For example, the task server needs it to provide task 
info capabilities.

Thanks,
Bas
