I agree - I'd never boot /boot into lvm. If there's some problem, and I've
seen them, it may not have the lvm driver loaded, and then you're hosed.

Take a clue from the default partition layout that install wants to use.
Remember, in / will be *all* of your o/s, and third party software, and
updates.... And /var, unless that's a separate partition, with all your
logs, which can sometimes get *very* big. If you've got the space, give it
100G or 200G.

I like /usr as a partition, and I used to like /var as one.
