Actually, the more I think about it, using bootcode -p to write the

smart, it will wipe out any existing stuff on that EFI partition,

utilities or operating systems, including device drivers.
The safer way is to mount that partition and copy the boot1.efi file
to it.
Pretty sure that's not done as you cant guarantee fat support is
available.
In the kernel, you mean? True. But odds are good that someone with a
custom kernel without msdosfs will understand the implications of
overwriting the EFI partition.
And of course it is safe to create an EFI partition, it would only be
a problem if one already existed with some extra files on it.
Yes, we remove msdosfs here and it would be PITA to have to add it back
in just to support writing EFI boot fs.
So personally I much prefer the current method. For those that want to
play with the EFI partition then they can do the manual update step
instead easily enough.
