By default, makefs(8) has very few spare inodes in its output images, which is fine for static filesystems, but not so great for VM images where many more files will be added. Make makefs(8) use the same default settings as newfs(8) when creating images with free space -- there isn't much point to leaving free space on the image if you can't put files there. If no free space is requested, use current behavior of a minimal number of available inodes. Reviewed by: manu MFC after: 3 weeks Differential Revision: https://reviews.freebsd.org/D29492
