It's easier if you skip the ones by Hans and their immediate followups :) (Nothing personal, it's that Hans is mostly justifying reiser4's behaviour, and the posts you really need to read aren't about reiser4). > > It's already been tried.

Somewhere deep in that thread is a discussion between Al Viro and Linus on it. > A new mount flag indicating that it's only to be followed down if > there's a slash after the mountpoint? The new flag would indicate more than that: These mounts should be detachable in the sense that deleting the file is possible, and perhaps renamable/linkable too. That's the stuff Al Viro discusses in some detail in the big thread. Ideally we'd like automounting, a bit like the Hurd's translators. Attached to files (using an xattr or something, and executed with the uid/gid of the file owner), and also per-user "pattern->action" options for matching files with a certain type (e.g. tgz/zip/deb/rpm/xml). But that can be added much later, as it's an orthogonal feature. -- Jamie - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
