dumpdev default

[Aristedes Maniatis]

The manual states that dumpdev "AUTO is the default as of FreeBSD 6.0" [1]

However:

# uname -a
FreeBSD xxxxxx 9.0-RELEASE FreeBSD 9.0-RELEASE #0: Tue Jan  3 07:46:30 UTC 2012     root at farrell.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC  amd64

# grep dumpdev /etc/defaults/rc.conf
dumpdev="NO"		# Device to crashdump to (device name, AUTO, or NO).
savecore_flags=""	# Used if dumpdev is enabled above, and present.


It looks like NO is still the default. Is there a reason why this should not be turned on even for production machines? I haven't read about any side effects, but it seems to be off by default for some reason.


Please cc me on any responses since I'm not currently subscribed.

Cheers
Ari
