If you remove files that are also duplicated on the host (assuption:
host distro + version = guest distro + version) then you can make
things MUCH smaller :-)

$ febootstrap --names bash systemd yum
$ ll -h *
-rw-rw-r--. 1 rjones rjones 4.6M Oct 16 08:44 base.img
-rw-rw-r--. 1 rjones rjones 630K Oct 16 08:44 hostfiles

# To reconstruct the image before boot:
$ febootstrap-supermin-helper -f cpio base.img hostfiles x86_64 kernel.out initrd.out
$ ll -h kernel.out initrd.out 
-rw-r--r--. 1 rjones rjones 293M Oct 16 08:46 initrd.out
lrwxrwxrwx. 1 rjones rjones   33 Oct 16 08:46 kernel.out -> /boot/vmlinuz-3.6.1-1.fc18.x86_64
