This is off topic, but since you asked...
I set up my Ubuntu box with full-disk encryption, I didn't see that option when I installed PC-BSD (it has swap-partition encryption though). Could be that I didn't look hard enough.
And PC-BSD is a bit moody for my taste - things that work one day won't work the next, but may again the following day (unimportant things like logging in to a particular DE/WM session, logging off/shutting down). I am currently also unable to install any of the system updates.
But I'm still learning. All in all, I like this system, although I'm not going to replace my Linux installation with it, at least not any time soon. Maybe I'll try a fresh install next, or possibly building a FreeBSD system from scratch. Or - oh horror
- I'll take a look at what the creators of this fine tool have to offer.
