But far more than a lab it is VERY useful in large memory configuration server farms where tossing 400MB+ of disk on every machine for a dedicated swap partition because you might need to capture a dump is just not a good option. > > This implementation will provide a kernel netdump client, including > hooks for some NIC drivers, and support for configuration with > dumpon(8).
