The linux guys are very anti-dump.   Personally, I find that 95% of the
time console output (and I think a logging serial console is essential)  
gives you all the info you need anyhow, and the other 5% of the time, 
I don't seem to be able to get anyone else to help me.  

The current crashdump tool, kdump, lets you copy the kernel to a partition,
or even over the network to somewhere else.  

But personally, I don't save dumps under Linux, just 'cause they change 
crashdump utilities every two years, and because nobody seems to know how to
do anything with them.  

FreeBSD is superior in this regard,  getting a backtrace out of a FreeBSD
dump is trivial.
