Crazy idea: why not just provide the user with an example .gdbinit
that does these things? For Isilon it makes more sense to tack on
additional paths (which we already do in our internal directions), and
others potentially are doing similar *shrugs*, so as long as the
example makes sense, I'd stick with it.
I would probably setup things in such a way that the old default
is kept though because I'm sure that there's someone out there that's
using it (even it it's not *the best* default per how we prefix things
in ports).
Thanks!
