The cost of atime on UFS and ZFS is quite different. While I
understand that consistency is a plus, I do think that there
is good reason to have different defaults for UFS and ZFS.
It would be good if there was a global parameter which let
the user choose the atime setting for all file-systems where
this setting is not overridden. Such a parameter could be
OFF (noatime) for ZFS and ON for UFS by default, but with
a short explanation about the consequences and a way to
toggle this setting if desired.
