+Greater use of blkid / libblkid
+-------------------------------
+
+guestfs_zero should use wipefs. See wipefs(8).
+
+There are various useful functions in libblkid for listing partitions,
+devices etc which we are essentially duplicating in the daemon. It
+would make more sense to just use libblkid for this.
+
+There are some places where we call out to the 'blkid' program. This
+might be replaced by direct use of the library (if this is easier).
+
+Visualization
+-------------
+
+Eric Sandeen pointed out the blktrace tool which is a better way of
+capturing traces than using patched qemu (see
+contrib/visualize-alignment). We would still use the same
+visualization tools in conjunction with blktrace traces.
