It looks like Freebsd allows user to toggle between
ddb and remote gdb. This is unlike netbd, where we
need to define the compile time option as to whether
we want DDB or KGDB.
 the problem with this feature is that in kgdb mode,
the system will wait for a 'c' on the remote machine's
gdb prompt before continuing with the boot-up and will
be stuck if there is no remote machine on the serial
port. Im interested in getting the system up with no
remote machine attached to the serial port and to plug
into the machine's serial port only in case of a
panic.
is there any architectural reason why this
cannot/isn't done in netbsd? Id appreciare any help on
this.
thanks
