I don't know of a way to do this that is already built into shipped rancid.

I've always held the view that some things are just not generic enough
or detectable enough to be shipped out to everyone, so you get to
maintain a few forks with your own customization. And there are nowadays
so many IOSes with different behaviours....

You probably want to add something like this to ShowFlash:

  next if (/coredumpinfo\/coredump.cfg\$/);

Untested of course so double check my regexes :-)

Rancid could really benefit from some kind of call-out mechanism where
we can add our own local tweaks and keep them out of the main code, but
unfortunately 2.3.x doesn't have this.

Perhaps a worthy addition to the 3.0 series!
