There are special dependency requirements for do_package,
do_packagedata and RDEPENDS are actually only really mapped 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.
Is there not already a mechanism for generically saying "I need <this> task of
<that> recipe to be completed before my <such-and-such> task can run" of which
DEPENDS and RDEPENDS are simply short-hand notations?

If "yes" (and I understand the discussion correctly) couldn't that be employed

If "no" (and I understand the discussion correctly) wouldn't adding such a
mechanism be a possible solution. The use of which, hopefully, would make it
easier for a user to understand what's going on (without requiring ad-hoc
knowledge of the system)?
