Comment 4 for bug 1281588

> when I log into Unity after a reboot, my hard drive audibly spins down and then immediately back up.

That sounds consistent with my objection in https://code.launchpad.net/~psusi/ubuntu/trusty/udisks2/fix-standby/+merge/206951 and on devkit-devel@. I don't think that E2h is the command that we actually want for setting the standby timeout.
