Only have this in the dump directory:
vega# ll /var/crash
-rw-r--r-- 1 root wheel 5 Sep 19 00:24 minfree
vega# cat /var/crash/minfree
No vmcore, but haven't seen any system crash anyway.
I use the system defaults:
dumpdev="AUTO" # Device to crashdump to (device name, AUTO, or
dumpdir="/var/crash" # Directory where crash dumps are to be stored
savecore_flags="" # Used if dumpdev is enabled above, and present.
