: I'm not sure I buy this argument, I'm afraid.  Part of the advantage of 
: having all this done automatically on the as-shipped release media is that 
: end users don't have to be interested in debugging - crashinfo(8) does 
: most of the work for them.  There's no easy way to actually determine 
: figures, but even if say only 10-15% of crashes can be diagnosed and 
: corrected just from the output of crashinfo(8) then that's a huge win for 
: the project as a whole. I'm guessing 10-15% is not unrealistic.
: I appreciate the issue about filling partitions is a valid one.  Would a 
: possible compromise be that on release media, crashinfo(8) or similar will 
: default to only keeping the most recent coredump or similar?  Given /var 
: now defaults to 4GB, Defaulting to keeping a single core is probably 
: acceptable.

Furthermore, if we aren't interested in crash dumps by default, why do
we install the huge .symbols files?
