Clear message


Based on the delivery of EncryptedPrivateDirectory in Ubuntu Intrepid, this specification describes the next steps to extend that work to provide a seamless mechanism for encrypting a user's entire home directory.

Release Note

This section should include a paragraph describing the end-user impact of this change. It is meant to be included in the release notes of the first release in which it is implemented. (Not all of these will actually be included in the release notes, at the release manager's discretion; but writing them is a useful exercise.)

It is mandatory.


This should cover the _why_: why is this change being proposed, what justifies it, where we see this justified.

Use Cases



You can have subsections that better describe specific parts of the issue.


This section should describe a plan of action (the "how") to implement the changes discussed. Could include subsections like:

UI Changes

Should cover changes required to the UI, or specific UI that is required to implement this

Code Changes

Code changes should include an overview of what needs to change, and in some cases even the specific details.



  • data migration, if any
  • redirects from old URLs to new ones, if any
  • how users will be pointed to the new way of doing things, if necessary.

Test/Demo Plan

As of 2008-12-02, you can test this by:

  1. Install the adduser and ecryptfs-utils packages in the following PPA:

  2. Add a user with an encrypted home directory as root, with:
    •  # adduser --encrypt-home testuser 

  3. Login as testuser on the console, through the GUI, and via ssh. Ensure that all programs work as expected. Log out of the console/GUI/ssh. Ensure that the home directory is not mounted and that the data stored in /home/testuser/.Private is encrypted.

Unresolved issues

There are two other specifications, solving related issues:
