I hate this as well but there are technical reasons to do so, I'm afraid
AFAIK ext2, unlike ufs and ffs, doesn't reserve space for a bootloader
except block 0 of a partition. I hope I am wrong here, but I haven't found
anything in that direction.
That means that a two stage boot process, like Ultrix and NetBSD do it, is
a no go if you want to have an ext2 filesystem as the first partition on
Maybe I am making the wrong assumptions here and I'd appreciate if someone
with more knowledge of ext2 can correct me.
