I noticed that using the DestroyFVKeyOnStandby option for FileVault 2 in terminal no longer works since upgrading to Mavericks. Usually you type the following in terminal:

sudo pmset -a DestroyFVKeyOnStandby 1 | sudo pmset -a hibernatemode 25

The first command is suppose to cause the FileVault key to be destroyed when you put your Mac to sleep. The second one causes the system to store a copy of memory to the disk, and will remove power to memory. After you close your MacBook or put your desktop Mac (10.8.5) to sleep after a few seconds then tried to open the lid / turn it on you would have 2 separate login screens.

One is the FileVault login window, the second is the standard OSX login prompt.

Since upgrading to Mavericks however this does not work. The Mac wakes up almost instantly and doesn't prompt for the FileVault password. Other settings I've played such as changing the timeout for sleep doesn't seem to affect it. My current "pmset -g live" stats are:

DestroyFVKeyOnStandby     1
Active Profiles:
AC Power      -1*
Currently in use:
hibernatemode        25
halfdim              1
womp                 1
networkoversleep     0
sleep                15 
Sleep On Power Button 1
ttyskeepawake        1
hibernatefile        /var/vm/sleepimage
autorestart          1
disksleep            10
displaysleep         10

Was this purposely removed from Mavericks? Is it a bug? Can't seem to find the answer anywhere else.
