Since we also default to SU-no-J, power failure can be quite bad during, 
say, installworld.
With / noatime, I had my RPI2 lose files like /usr/bin/cmp, /bin/ls, and 
/bin/cat during a power loss.
Since it's not even possible to cleanly shut down this platform, I'm for 
enabling noatime for / on
at least for RPI and RPI2 platforms.
