You state that "proven" is the same as "good", but why you do so escapes me. In general, you can easily prove that black =3D=3D white (etc.) by such illogical reasoning. The reasoning in fact is that file systems which are out in the field for years have _known_ properties, are proven to work with some amount of software, possibly including software that specicially has workarounds for filesystem shortcomins (i.e. squid with it's multi-dir-hierarchy, which is just a workaround for basically all non-reiserfs filesystems, and now also for reiserfs3 filesystems, which also doesn't cope with millions of files in a dir, as opposed to the original claims by it's developers). This is cerftainly true for microsofts filesystems: you know what to expect =66rom vfat or ntfs, for example. For new filesystems, the issue is completely different. Look at the "file is a directory" approach that formerly was the default in reiserfs. This breaks a number of programs, despite the expectancy by the reiserfs authors that this is not the case (in my experience, stat "path/." to quickly check wether sth. is a file or a directory is pretty common). Unless the filesystem is in the field for some time these bugs will not be found. --=20 The choice of a -----=3D=3D- _GNU_ ----=3D=3D-- _ generation Marc Lehmann ---=3D=3D---(_)__ __ ____ __ pcg@goof.com --=3D=3D---/ / _ \/ // /\ \/ / http://schmorp.de/ -=3D=3D=3D=3D=3D/_/_//_/\_,_/ /_/\_\ XX11-RIPE
