Defaults in 10.0 ZFS through bsdinstall

[Marcus Reid]

Hi,

I noticed a couple of things with the ZFS defaults that result from
using the new installer in 10.0-BETA3.

One, atime is turned off everywhere by default.  There was a thread on
this list on June 8 with a subject of 'Changing the default for ZFS
atime to off?', and from what I can tell the idea of turning off atime
by default was not a popular one.

Two, and probably less controversial, is that fletcher4 is specified
exlicitly on the root pool, even though it is default (wouldn't you just
want to go with the default, in case it changes?)
