Encrypting home dir + swap, and using a /tmp ram disk, is sufficient even for data protection act requirements. Everything written outside those three areas are operating system files only.

Fair point, but regardless you can always return an online purchase within 7 days if you change your mind. http://www.out-law.com/page-430 You'll lose the cost of returning the item, but not the delivery cost.

Your understanding seems right to me, and TBH, an encrypted /home or just your own folder would be enough for me, personally. Actually I don't do it - I'm not that paranoid - but yes, I expect it'd be faster.

Other than that I would just use home dir encryption. I am using home dir encryption for the first time on my new lucid install. Your home dir is decripted when you login to X windows - i.e the normal desktop gdm login. Note that you cant use automatic gdm login, there is a warning in the lucid installer against this. Using just the encrypted home dir has worked fine for me and I have not had any access or performance problems. -- John Stevenson jr0cket.com leanagilemachine.com -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/
[ubuntu-uk] Encrypt whole disk or just home dir?
I'm seeking advice and wisdom! My laptop is currently fully encrypted. It has a partition that contains a crypt that contains some logical volumes that contain all file systems except /boot It occurs to me I might be better off just encrypting my home directory. I think this might improve performance as the system would not have to decrypt the operating system files. Not sure how big an impact this would have. Presumably I would no longer get prompted for a pass phrase every time I switch the machine on. Very secure, but annoying! Am I right in thinking that the home dir encryption effectively uses my password to protect it, or would I have to enter my password and an encryption pass phrase every time I log on? Any thoughts?

It's a pretty good solution, and only has occasional digital audio output issues which require restarting XBMC. I plan to replace the Keysonic with a PS3 remote and bluetooth dongle and mount the Revo on the rear of the television. Eventually. Right now, it ain't broke.
