Does that make it clearer why we need this?
I certainly understand it more.. I'm just struggling with how to

The rules in some ways are simple, it comes down to:

If your postinstall can execute at rootfs creation time rather than on
target but depends on a native tool in order to execute, you need to
list that tool in PACKAGE_WRITE_DEPENDS.
Looking at this description, it is not at all clear to me why the
variable is named PACKAGE_WRITE_DEPENDS. From the description, the
things listed in it are dependencies of do_rootfs, not of
do_package_write_*, even if it happens to be implemented that way.

I like PS_NATIVE_DEPENDS better. Just my 2 cents.
PACKAGE_SCRIPTS_DEPENDS maps better to what they are intended to be
used for, I think.
