I generally belive that such meta-data should be in the partition so people don't get surprised that dd if=/dev/da0p1 of=/dev/da1p7 bs=1m doesn't do what they want. So while the answer to your question technically is "yes", I belive we shouldn't use that space unless we have a very good reason. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
