Subject: retrofitting LUKS encryption on installed system

I've got a F19 installation that I'd like to turn into a fully encrypted
system with LUKS. 

There are many howtos on the web for encrypting a partition, but they
all show doing it to /home.

No, just re-install.
One partition with /boot and another with an encrypted volume-group, holding /, swap and the rest.

But before embarking on that trip, do you really need full disk encryption?
I mean, the content of /usr is on any fedora-cd ;-) And when up-and-running, everything is unlocked.

The only valid reason I can think about, is that other people have physically access to your machine and could get root-access by booting from cd/dvd, and might alter your system.

It surely works, but at a performance price. And the certainty that you have to enter the LUKS-key each time you boot.
