I wrote the original 'nextboot to use block 1 (ususally unused)
to avoid under all circumstances writing into the filesystem.
Also, part of the weakness of the current system is that it presumes you know
which IS the root filesystem. The original nextboot took as part of the
information it loaded from block 1 (assumuing it checked out as a boot-spec
block) the partition to use as the root. If the root partition is totally hosed
you may not be able to READ /boot/{anything}. The original nextboot
was really a local hack to fix a local problem, but I was thinking of making it
more
'acceptable' to the world as a whole by making it look for a DOS partition of
some type, and {length 1,location 1} before loading information.
I deliberatly kept this information outside the filesystem.
