No, 'if BUILDTIME' can be used with any package. It just means, that The
packages will be ordered accordingly at build-time but no dependency will
be added to the resulting .ipk File.

This was how I understand it two.
The last time I used this feature is to long ago, to be sure ;-)
With recent release (ptxdist-2019.06.0) the package gets installed until I remove prompt line.

I try to pin my problem down.
Where is the post processing which removes the dependencies with BUILDTIME?
I mean, in 'scripts/lib/ptxd_lib_dgen.sh' there is 'PTXDIST_DEP_TARGET="run" ptxd_kconfig_dep_all "${config[@]}"',
but the automatically selected package will stick if it has a prompt.

I think I understand way you're trying to do.  Consider this example:

config FOO
	tristate
	select BAR if BUILDTIME
	prompt "foo"

If 'foo' is enabled, then so is 'bar'. This means both symbols are enabled
in the ptxconfig. This also means that both packages will be in the default
package ist for the rootfs. That cannot be changed.
What 'if BUILDTIME' means is, that
1. The make dependencies are a bit more relaxed, which can improve the
   build time.
2. There is no dependency for this in the ipkg. So you could remove the
   package 'bar' at runtime without removing 'foo'.

Creating an image with 'foo' but without 'bar' is not easily done. I
suppose you could create your own image with:

IMAGE_BLA_PKGS := $(filter-out bar,$(PTX_PACKAGES_INSTALL))

Regards,
Michael
