--- Comment #4 from Steffen Winterfeldt snwint@suse.com --- mkdud actually warns you about this:
# mkdud --force ... rpm-4.*.rpm [...] Installation System: *** Warning: includes /usr/src/packages. *** /bin/rpm
Without '--force' mkdud will fix the dud to prevent these issues. (The mentioned directory must not exist in the install environment.)
But unfortunately you need '--force' to build a dud for the currently broken TW iso. :-(
