No, you need to use collections as well. There is some stuff about this in
the documentation.

Why? Sysroot is not used for the target rootfs. Do the files conflict with
other packages? In this case, you could define a custom <pkg>.install.post
target in the package makefile. That's the stage that copies the files to
sysroot-target.
