I've changed the default value of ddb_enable to YES so we now load ddb
scripts from ddb.conf by default. Developers expecting to perform
active deugging should add ddb_enable=3DNO or change the script to not
perform at textdump and reboot the machine.
This is another step toward hopefully shipping 8.0 with DDB built
in and generating useful crash dumps. The security implications of
doing so need to be carefully considered and in particular the GENERIC
kernel will probably want to be shipped with at least the options
DDB_UNATTENDED and SC_DISABLE_KDBKEY.
The fact that the watchdog driver changes it's behavior based on
DDB_UNATTENDED is probably a bug that should be fixed.

Modified files:
etc/defaults rc.conf=20
Log:
Change the default of ddb_enable to YES so we default to generating textd=
umps
on panic. This means you get a potentially useful dump even if your syst=
em
is running X when you panic.
