Do you have integration with PAM?  I assume you must if you are
encrypting your home directory, since there would need to have some
way to insert the key to unlock your home directory as part of
single-sign on.  Or are you only encrypting something like the Private
directory on your home directory, and entering the password separately
fromo the login password.

One of the really nice things of the ecryptfs integration, especialy
on Ubuntu (and I don't remember if Tyler was responsible for that
work; if so, kudos!) wasthat it was particularly eeamless.
