I was able to complete an install of F17-Alpha just now with all lvm. I
had to force the use of MSDOS disklabel instead of GPT (used parted's
mklabel command on tty2 while the anaconda prerelease warning was on
screen on tty6), then I used custom partitioning to create a single
partition on disk as an lvm pv. I then created logical volumes for root,
swap, and home. The rest of installation went smoothly, as did the
reboot.
