boot lvm squeeze

[Soren Orel]

I've downloaded a weekly snapshot about squeeze:
http://cdimage.debian.org/cdimage/weekly-builds/amd64/bt-cd/
but I just want to ask, I've heard that I could simply install squeeze, and
boot from LVM, does GRUB2 does this? Is it in squeeze by default? (I mean I
just can install testing and not have to create a /boot on another partition
than the LVM partition?)
