I just looked at this.

Does febootstrap do some sort of unrpm? Does it call %pre/%post install
scripts? 

zypper alone can not be used because it calls rpm, which does chroot.
It can however download the required rpms and place them into a
directory:

zypper \
        --verbose \
        --verbose \
        --gpg-auto-import-keys \
        --root /dev/shm/${LOGNAME} \
        --reposd-dir /etc/zypp/repos.d \
        --pkg-cache-dir /dev/shm/${LOGNAME}--pkg-cache-dir \
        --non-interactive \
        install \
        --auto-agree-with-licenses \
        --no-recommends \
        --download-only \
        kernel-default

So what do you suggest to do on a system with zypper/libzypp?
