My format consists of one platform neutral header of 512 bytes, which among other things tell you what the platform is. It places no restrictions on what the actual dump contains, and consequently if a particular platform needs metadata, it is perfectly possible to add platform specific headers for that purpose. But as I already said in the commit message: I disclaim all maintainer ship in this area, I just passed by because the devicedriver interface needed to be cleaned up. If you have a better idea for an on-disk format: 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.
