Hi: 1) I was thinking, what is the performance penalty of storing data on an encrypted device? Sure, for writing documents, coding and stuff, I guess the performance loss is insignificant, but for music and video which then needs to be decrypted and then decoded, is this a problem? 2) One thing is to create an entire encrypted device for /home. But that have the unfortunate consequence that other user's data is unencrypted once the system is up. What would be more appropriate is a solution where each home-dir is an encrypted mfs which is decrypted and mounted when the user log in, is this possible? If not, then the alternative would be to have a private mfs in the user's home dir which is mounted after login, but I think yet the user needs root access to mount encrypted devices. Is there any possibility for users to mount their own encrypted mfs?
