potential df issues in 8-stable

[krad]

Just updated my system last night to 8-stable. Now im seeing a minor issue
with df in that it doesnt output anything. I'm a pure zfs based system.

# df -h
#

# zfs list | grep system

UFS is ok though

# mount /dev/zvol/system/test2 /mnt/

it looks like df is finding the zfs file systems
