I would like to have a disk that:
- has Ubuntu installed
- is fully encrypted
- is setup in such a way as to make denial of the existence of the Ubuntu install plausible
Truecrypt provides the last two features but only for Windows: http://www.truecrypt.org/docs/?s=sys-encryption-supported-os
The alternate installer for Ubuntu provides the first two features but not the last.
I imagine that plausible deniability would be achieved by, at least:
- Having two installs of Ubuntu and 2 passphrases (or keyfiles) which would unencrypt each one.
- Moving any unencrypted data (such as /boot) onto a USB stick
Are there any programs out there which support this feature set for Ubuntu?
