>Description:
the man page for rc.conf:
dumpdev (str) Indicates the device (usually a swap partition) to
which a crash dump should be written in the event of a system
crash. If the value of this variable is ``AUTO'', the first
suitable swap device listed in /etc/fstab will be used as
dump device. Otherwise, the value of this variable is passed
as the argument to dumpon(8). To disable crash dumps, set
this variable to ``NO''.
but the /etc/rc.d/savecore script will fail if dumpdev="AUTO", since
the code described in the man page seems not to be implemented. I
couldn't get dumpon to work either.
>How-To-Repeat:
set dumpdev="AUTO" in rc.conf
crash the machine and you won't be able to retrieve a crash dump (grr)
>Fix:
Implement the AUTO in savecore (and dumpon?), or change the manual
like this:
