Bottom up is that you strictly define before use (as the opposite of
top-down where you use before you define; as in the two programming

For instance, if you use stuff from some header that defines linked
lists "list.h", and some header that defines linked FooBars "foobar.h",
then you include them in that order. In this case you can assume that
"foobar.h" probably includes "list.h", and this defines the order, but
there are cases where some intuition is needed; for instance I would
include a "long-integers.h" before a "complex-gui.h".

Ehm yes, you are right. I was concentrating on thinking the former is
more general than the latter, in the sense that one is about the whole
OS and the other only about I/O. Now if both were actually in the same
category they would go in that order :-)
