We got bitten a few times - Catalina's a good example - heaps of
developers use it.
You can't go round 'educating' developers to make exceptions - it's just
wasting peoples time and mindpower to save some tape space...
I just got rid of the core rule altogether... Maybe we back up
another gig of core files over 20TB of data, about 0.0025 of a tape per
week...
The other option is to replace the skip directive with compressasm,
core files usually scrunch up really well.
