I believe the mandatory update is like other minor upgrades - fixes
bugs. Sort of 4.05. I don't know which images it patches and whether any
of those images are also patched by 4.1.  It's not that much trouble to
do it; why do you want to do it in the wrong order? I think that doing
4.1 before the mandatory patch is like upgrading to 4.2 from 4.0 and
then going back and applying the 4.1 upgrade. There may very well be
later patches in the 4.1 upgrade to code that was also patched to fix
different problems in the mandatory update and doing them in the wrong
order sounds like a way to get a slightly broken image or two.

If you are asking because you accidentally forgot the mandatory update
and have already done 4.1, then forgive my tone; I misunderstood.  If
that is your problem, the paranoid method would be to back out your 4.1
update and do the mandatory update, then re-do 4.1. To avoid that, you
would need to find out every file that is patched by each of these and
see if there are any overlaps or not. Since I hear there are a good
number of patches in 4.1, you may be out of luck.
