I wanted a way to encrypt my user folder e.g. (/User/sid/*) and have Mac OS X auto mount it based off my login credentials. Since that folder also contains profile info, I suspect it would need to be decrypted, mounted right at login time itself.
My guess is truecrypt would work but
- No idea about autologin
- Truecrypt may require the entire 50GB allocated at the start and may kill timemachine by backing up all 50GB each time I change even a single byte inside the encrypted volume.
Honestly, I wish Apple has left in FileVault 1 and 2 and allowed users to pick their choice.
I know Lion has FileVault2 but that encrypts the entire system. I've got the macbook setup to dual boot into Windows 7 (which is whole disk encrypted with Truecrypt). Since I had to do that, I had to revert from a GPT style to a MBR style for the hard drive and FileVault2 cannot work on MBR systems. Had to say that because someone would throw a fit and say "turn on FileVault2".
