Your boot filesystem needs to have roughly the following layout:

/boot.config
/boot/beastie.4th
/boot/device.hints
/boot/frames.4th
/boot/kernel/kernel
/boot/kernel/zfs.ko
/boot/loader
/boot/loader.4th
/boot/loader.conf
/boot/loader.rc
/boot/screen.4th
/boot/support.4th
/etc/fstab

You can't mount that somewhere and have it "just work" - you'll need
to mount it somewhere out of the way and have symlinks in your root
directory.  Not very convenient.  Easier to just use UFS on your root
filesystem, and use ZFS where it can make a difference (/var,
/usr/local, /home etc)

Your average root filesystem is small and fairly quiet, so the chances
of something going wrong are low and it only takes an instant to fsck.
