Your question is still a bit unclear: do you want to have just the
_root_ partition as ZFS? That should be easy, just booting a kernel
which understands ZFS and can mount that as /.

Do you also want to have the _boot_ partition there? I.e. that
partition where the kernel images and the initramfs go. Then your
boot loader (most probably GRUB?) also should be able to understand
ZFS -- at least to a certain extent. GRUB can read ZFS since 1.99.
The one current in Debian stable is 2.02 -- so your chances seem
good on both fronts...

Cheers
