output of zpool and gpart commands

I'm using five disks in my system (ada0, ada1 and ada4 are SSDs, ada2 and a=
da3
conventional disks).=20

ada2, ada3 and ada4 hold one freebsd-zfs partition each. ada2 and ada3 cont=
ain
the data and ada4 is used for L2ARC.

ada0 and ada1 hold two freebsd-zfs partitions each. Partition one on each d=
isk
is used for a mirrored intent log for the data pool. Partition two holds the
mirrored root pool.

I have set the bootfs property on the pool root but not on the pool data.
gptzfsboot tries to load data/boot/gptzfsloader (and fails). It fails even =
when
there you put zfsloader into data/boot.

After reordering the GPT entries the system boots fine. I think this behavi=
our
should be documented in gptzfsboot(8).

The attached was done with the reordered gpt.
