Rationale
Currently the Ubuntu Desktop installer does not allow the user to set up whole disk encryption (with lvm/luks). However, this is easily done though the "Guided - use entire disk and set up encrypted LVM" option in the alternate installer. This should also be possible via the desktop installer.
Can you please tell why disk encryption is important and what it really does. I don't think everyone knows.
I think that if there would be such an option, there should be a "what's this?" next to it. The GUI installer is intended to be user friendly, please keep it so.
If someone gains physical access to your machine, there is no way to stop them from compromising it. Even with full disk encryption they could rewrite the decryption software with an exploit (cf. the "evil maid" attack).
Full disk encryption has limited use cases. Anyone who needs it can probably use the alternate install, but I suppose it wouldn't hurt to have it behind some "advanced" button in the graphical installer too.
Policies for encrypted removable drives, however, seem like a good idea.
Appearently there is also no way to install Ubuntu Netbook Remix with whole disk encryption.
Home dir encryption is not enough, as private data can be placed in swap. Also, some of the files under /var, /etc, /root, etc. can be very sensitive also.
Lots of corporations and governments require that all laptops/netbooks have whole disk encryption set up. And this is good. It is a shame, that they cannot use Ubuntu Desktop Installer because of this lacking feature. Especially considering how trivial it must be to implement, when the code is already there in the alternate installer.
I almost can't believe this hasn't been implemented yet. It's ridiculous that with every new version of Ubuntu I have to carry around two discs: one liveCD to ensure hardware compatibility before I install, and one "alternate" CD to actually do the install (with full-disk encryption).
