It's probably to late to do that for jessie unless there is some major
breakage caused by that for UEFI systems (which I don't know, not being
familiar with UEFI).

We'd also have to check, if shipping systemd-efi-boot-generator has
other side-effects. A quick glance at its sources suggests it  generates
a mount unit for /boot and I don't know how that would interfere with
the UEFI/boot loader integration in Debian.

In any case, it's probably good to have some input from our UEFI
experts, so CCed Steve.
