Hi Wookey (and others that might be interested)
With Mutlistrap and qemu we've gotten live-build to be able to cross build most of our images. The next step however in nano is to pull out a number of the packages and in some cases replace them with busybox components to get an even smaller rootfs. An important part of this is to not include recommends AND not take into account required packages. It would appear that multistrap is unable to ignore the required packages. There are a number of them.
You will also note in the log below a number of the busybox replacements explicitly conflict with their non-busybox brethren. In the Multistrap package list, the non-busybox versions are not listed yet Multistrap is pulling them in (as well as others I had removed).
Grepping through the Multistrap perl source I don't see a way forward but I know you're the expert here. I would appreciate your thoughts.
Here's the log :

A little update and clarification.
omitrequired is the option to not consider the Priority: required packages.
However once added additional packages are getting pulled into the build. From the snippet below, we can see recommended and suggested aren't getting picked up which is good, but there's this extra packages list and that IS getting picked up. According to the docs, extra packages should be packages which are user listed however none of these are user listed. Is it Priority: important packages getting pulled in? (ref :http://wiki.debian.org/Multistrap Look at the debootstrap comparison section)

The other troubling part is once one issues a dist-upgrade the busybox versions of grep, hostname, mount and tar are up for being removed, never mind all are set as Priority: required and set as conflicting and replacement for their named package. I'd like to think once installed these kind of packages would stick especially if their are Priority: required. Here's a snippet:
