>Description:
In 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''.
Problem is, the AUTO switch is no implemented, neither for
/etc/rc.d/savecore nor /etc/rc.d/dumpon. (it is in 6-current, but not
in 5.4-stable)
>How-To-Repeat:
set dumpdev="AUTO" in /etc/rc.onf
crash machine
there will be an error when trying to retrieve the kernel dump
>Fix:
Either MFC the auto stuff for the named rc.d scripts (best), or apply
this trivial man page patch:
