Updated FileVault 2 status check Extension Attribute now available

I've updated my FileVault 2 status check EA, to better handle Macs with multiple encrypted volumes. I'd noticed that I was occasionally seeing some Macs reported by the EA as being FileVault 2 encrypted, but on investigation, the encrypted drive was actually a non-boot volume (like an encrypted Time Machine backup.) I've addressed the issue by having the EA check specifically for the boot drive's FileVault 2 status.

The updated EA is available from the following address:
