Is there an optimal method of making a complete copy of a ZFS, aside from the conventional methods (tar, cpio)? We have an existing ZFS that was not created with the optimal recordsize. We wish to create a new ZFS with the optimal recordsize (8k), and copy all the data from the existing ZFS to

Evince likes to fuzz a number of PDFs. I too can't seem to nail the problems, but it seems that a number of PDFs from SUN have this problem (very wrong character spacing), and they all have been generated using FrameMaker. PDFs generated using TeX/LaTeX are *usually* ok. This message posted
