Fortunately, the wayback machine still has it. Check out: http://web.archive.org/web/20021013181038/www.namesys.com/content_table.html Another good source for understanding the format is the reiserfs code in grub. It's read-only support, which makes the implementation quite small since it removes most of the complexity in the kernel implementation. If I recall correctly, the format is even described in the comments. Hans - Is this information still available at namesys.com? I understand that you're primarily supporting reiser4, but all the information previously online about reiser3 is still valuable. - -Jeff - -- Jeff Mahoney SuSE Labs -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFBUJbeLPWxlyuTD7IRAhDiAJ9K/L2sM3T7z4cU9t/oI/8NuXUiXwCfZmuN W4W60G5XqtO03rHjD4oVhq4= =lVWJ -----END PGP SIGNATURE-----
