I had to learn it the hard way, too (reading /etc/rc* files on
why there is no "core" file). You need to set the "dumpdev"
variable in /etc/rc.conf.
And I just had a look at
$PAGER /usr/src/sys/i386/conf/{GENERIC,LINT}
man savecore; man rc.conf
which doesn't look too intuitive. :) Is LINT in need of a
pointer to the rc.conf variable? Reading "man 4 ddb" doesn't
find "core" either and the one match for "dump" is not related to
the problem.

How about having DDB and DDB_UNATTENDED in GENERIC (together with
the handy INCLUDE_CONFIG_FILE), too? Those who don't enable
debugging info (by editing the kernel config file or make.conf)
or dumpdev (in /etc/rc.conf) won't get their root fs clobbered /
filled up. And those who experience failure situations they want
to report have less to do for delivering helpful information. Is
this acceptable "bloat" or completely useless since I don't know
about other dependencies and missed them?
