For example this blog entry mentions that an existing partition with
/Users can be encrypted, but it also says "secondary driver". Same remark has been mentioned in a few other blog posts I found via google.
So the question is: I have a single volume in my MBP, where the OS itself is installed, and it contains all the userdata too.
Can it be encrypted via
diskutil without data loss?
Rebooting is not an issue, just need automate the steps involved.
