Is it possible to have multiple filevault2-activated partitions on one disk? What I would like to have: A disk with the following systems on it:


OS X 10.8 (FV2-encrypted)
OS X 10.9 (FV2-encrypted)
Windows 7


When I try to start FV2-encryption on my secondary partition, OS X tells me that in some configurations FV2 cannot be activated. Do you know if this can be done? How?

Bonus question: The Bootcamp partition is not available in the boot menu after installing 10.9. Is it possible to have multiple OS X + Bootcamp live together on one disk?
It looks like probably not, based on a few search results :(

  FileVault 2 [...] only encrypts the startup drive. If you have
  additional drives or partitions, including a Windows partition created
  with Boot Camp, they will remain unencrypted.


This thread, however, is a bit encouraging: https://discussions.apple.com/thread/5644065

On page 2, someone links to https://github.com/jridgewell/unlock which might be useful. That is, you might be able to set up a pre-login step to unlock additional volumes.
