[oe] Dependency tracking - or - how to get rid of kexec-tools

[Nils Faerber]

Hi!
I just found a little bit of a problem and am now looking for the most
correct solution to it...
I am trying to build x11-image for a mipsel target. I am using the
dev-head and angstrom-2009 or DISTRO_VERSION = "2009.X-test-20090301"
respectively.
The problem is that this constellation includes kexec-tools-static for
something just that kexec-tools-1.101 does not support mipsel.
As far as I have seen it I will not make use of kexec-tools later on. I
just want to build a quite simple X11 image for that device.

So I can do two things:
1. Get rid of the dependency so that it will not be built. How can I
find out which dependency pulls in kexec-tools?

2. Upgrade kexec-tools to the version that is e.g. in Debian, like
kexec-tools_20080324.orig.tar.gz which now include mipsel support.

So, what to do now?
Even if 2. would be the best way to go I would still be interested how
one can trace this kind of dependency - sometimes I would be really
interested why certain packages are built.


PS: I am planning on submitting this mipsel machine support. What would
be the best way? Create a diff against dev-head and post here?

Cheers
