You don't need ddb to do that. you could do gdb on a crash dump.
Indeed, that's probably a lot easier for "the average person," because
i'm _quite_ sure that the average person is more familiar with GDB
than with ddb. 8-)
Sure, for debugging a kernel that's in the process of dying, ddb on
console is better than gdb on a crash dump (but remote kgdb on the
live kernel is better yet). However, do (perhaps: should) average
users be doing that?
One of the things I like about Digital UNIX (formerly DEC OSF/1) is
that after it crashes, when rebooting and saving the kernel core dump,
it also extracts 'interesting' bits of information into a text file
for easy perusal.
