I fixed some bugs that were reported to me: - create_compressed_fs should do padding to 512 bytes boundary - kernel panic in geom_ugz and added last uncompressed block caching (which should significantly speed up geom_ugz especially for large block sizes). Updated tarballs are available at http://people.freebsd.org/~fjoe/geom_ugz/ Thanks for your feedback! /fjoe
