I am not going to do anything of the sort which Pawel proposes because _if_ I wanted to handle this issue, I would do it with journaling which would also bring a lot of cryptographic benefit. But again, I'm not even planing on touching this one in the first place. If you want to write your own disk encryption, by all means go for it. -- 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.
