Hi,
from the faq: "Upon reboot, savecore(8)will attempt to save the
contents of the swap partition to a file in /var/crash"
savecore would be called by /etc/rc.
So which criterias must be fulfilled to make core dump upon reboot?
Does savecore look for special file names at special places? Who makes
the rule?
I'm not entirely sure I understand your question, the subject and the
body of your message don't seem to be completely related.
However, I think you may find the answers to your questions in
man 8 crash
Third paragraph (more or less, depending what one counts) tells what
conditions cause the in-RAM image to be written to disk in the swap
partition. If that happens, an attempt will be made to dump it to
physical disk upon reboot.
Note that on a modern system, /var is very often not large enough to
hold a core dump. If this is something you care about, you will need to
deal with it accordingly. (aren't we all glad that attachments are
stripped from misc@ postings now? "Hi, here's my 2G core dump. why did
it happen?")
