Hello: I have this crazy dream that I could, one day, mount SCO, Linux, and Solaris FS's under FreeBSD *and* run all this apps transparently by emulating. I now have more documentation about SCO filesystems, and HPFS: these two are also supported (partially) by Linux. What I really donīt have is documentation about FFS. Since fbsd seems to be ill suited for other filesystems, should "we" try to implement a standard Linux filesystem and derive the others from it, or should *we* try to use more documentation than Linux sources, and try to implement them from our VFS?
