boot loaders got fatter in the last few days

Hi,

I have just update one of my machines and noticed the booloaders files
got quite fat in the last few days, some by a big margin.

on an updated machine(r296993):

> ls -l /boot/*boot*
-r--r--r--  1 root  wheel    8192 Mar 18 16:47 /boot/boot
-r--r--r--  1 root  wheel     512 Mar 18 16:47 /boot/boot0
-r--r--r--  1 root  wheel     512 Mar 18 16:47 /boot/boot0sio
-r--r--r--  1 root  wheel     512 Mar 18 16:47 /boot/boot1
-r-xr-xr-x  1 root  wheel   72152 Mar 18 16:47 /boot/boot1.efi
-r--r--r--  1 root  wheel  819200 Mar 18 16:47 /boot/boot1.efifat
-r--r--r--  1 root  wheel    7680 Mar 18 16:47 /boot/boot2
-r--r--r--  1 root  wheel    1185 Mar 18 16:47 /boot/cdboot
-r--r--r--  1 root  wheel   85794 Mar 18 16:47 /boot/gptboot
-r--r--r--  1 root  wheel  110546 Mar 18 16:47 /boot/gptzfsboot
-r--r--r--  1 root  wheel  358400 Mar 18 16:47 /boot/pxeboot
-r--r--r--  1 root  wheel  341248 Mar 18 16:47 /boot/userboot.so
-r--r--r--  1 root  wheel   66048 Mar 18 16:47 /boot/zfsboot

from a machine I still have not updated(r296719):

> ls -l /boot/*boot*
-r--r--r--  1 root  wheel    8192 Mar 13 21:01 /boot/boot
-r--r--r--  1 root  wheel     512 Mar 13 21:01 /boot/boot0
-r--r--r--  1 root  wheel     512 Mar 13 21:01 /boot/boot0sio
-r--r--r--  1 root  wheel     512 Mar 13 21:01 /boot/boot1
-r-xr-xr-x  1 root  wheel   72152 Mar 13 21:01 /boot/boot1.efi
-r--r--r--  1 root  wheel  819200 Mar 13 21:01 /boot/boot1.efifat
-r--r--r--  1 root  wheel    7680 Mar 13 21:01 /boot/boot2
-r--r--r--  1 root  wheel    1185 Mar 13 21:01 /boot/cdboot
-r--r--r--  1 root  wheel   16059 Mar 13 21:01 /boot/gptboot
-r--r--r--  1 root  wheel   41511 Mar 13 21:01 /boot/gptzfsboot
-r--r--r--  1 root  wheel  288768 Mar 13 21:01 /boot/pxeboot
-r--r--r--  1 root  wheel  341208 Mar 13 21:01 /boot/userboot.so
-r--r--r--  1 root  wheel   66048 Mar 13 21:01 /boot/zfsboot

I noticed because mu gpt boot partition is 64K and gptzfsboot just
passed 100K.

Is this expected and I'm supposed to repartition or is this an unwanted
mistake?

Thanks in advance.
