+Detect a ZFS filesystem by looking for valid uberblocks.
+
+This support will appear in an upstream version of e2fsprogs.  For the
+moment however you will still need to locally patch you e2fsprogs packages.
+This patch applies cleanly to fc11's e2fsprogs-*-1.41.4-10 and should
+apply easily enough to the e2fsprogs from other distros.
