I'm attaching some rbuild files I used before:

into different modules is going to only hurt the development, not
make it easier. I already thought about that, but I'm afraid it won't
work.
Oh, actually, Marc Piulachs already implemented all of that in his
platform builder, so he's able to pick necessary modules with a click
of a mouse, and produce an installation CD consisting of such
"modules", and it indeed works. It just is not separated physically
in the tree itself.
WBR,

I would even like to go one step further in the
long run.
The current situation is that rosbuild takes about 10 minutes for a
build. With adding more code and more modules to our codebase, this
time will increase. If we wanted to do something like auto-
rejecting commits that break build it would lock the commit process
for this time on every commit.
Also as we get more developers and maybe start forming teams or
whatever, things will get problematic with our current "monolithic"
approach.
We should think of changing the build process, so that not the
whole system is rebuild everytime someone changes one module.
We currently treat reactos like one huge module, but it isn't. It's
a bunch of more or less independent things. A change in a usermode
dll should not lead to an notskrnl recompile, it just doesn't make
sense and only wastes time.
I think it would be better to seperate the components from each
other as much as possible and only compile the modules that have
been changed.
Of cause all modules somehow depend on each other, but mostly
through well defined interfaces. These are exposed by the headers
and import libraries. And those 2 are the problem atm.
It might be a good idea to completely separate the sdk from the os
itself. The sdk would contain both the headers and the spec files
to build the import libraries. If we made sure these are in a good
shape, we would eleminate most interdependencies as they should
only rarely change.
We could try to split the current reactos tree into seperate trees,
maybe like this:
sdk: headers, import library definitions, crt
core: rtl, freeldr, hal, ntoskrnl, boot drivers, ntdll, smss
drivers: other hardware drivers
win32core: win32k, video drivers, gdi32, user32, csrss
win32dll: the other win32 dlls
sound: everything related to sound
network: everything related to network
reactx
services
apps
Some of these trees could be optional, like network, sound, reactx
It might even allow to create a bootable core system without win32
stuff, booting into a simple native console.
Working with branches might as well profit from this.
Just my 2 cents,
Timo
