The former dracut ‘usrmove’ module has been renamed to ‘convertfs’. We need to carry that option for quite some time through future releases and want to name the module more generic for possible future needs in that category. This is the current version/build number: dracut-014-81.git20120202.fc17 Please build the custom dracut image now with: # dracut --force --add convertfs On the kernel commandline dracut now looks for: rd.convertfs In some cases, we still do not properly support multi-lib updates with the current testing repo, without adding also the i386 repository to the updated system; the f17-usrmove repo does not automatically copy the 32bit libs in the 64bit repo. This issue will not happen when all moves to rawhide. These known bugs are fixed: - rebuild of the dracut initramfs on the converted system had problems with optimized i686 libs, which is fixed now - the ntfs-3g was not part of the f17-usrmove repository and installing the old package on the converted system broke its symlink logic. The fixed package is built for f17-usrmove now. -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
