Ouch, I've just got bitten by this. I'm trying to update a 6.x machine
to 7-current, and couldn't install the kernel because there's no space
for in on the root file system. This is an old-style root file system of
256 MB. By fiddling around I've managed to free enough space, and I see
now that my new /boot/kernel's size is 106 MB! This means I can't hold
both kernel and kernel.old on the root file system.

This may need to be addressed in upgrade documents. (And others - for
example, tuning(7) still implicitly recommends a 128 MB root file system).
