remote debugging stubs

[Greg Buchholz]

        Has anyone out there ever used a serial console for debugging a
hurd translator at boot time?  I'm looking for the gdb debug stub
functions (getDebugChar, exceptionHandler, etc) that can be used before
the hurd is up and running (and after Mach boots).  Specifically, I want
to attach to an iso9660fs translator setup as a bootstrap filesystem.  If
anyone can point me in the right direction, I'd appreciate it.


Thanks,

Greg Buchholz
