Not addressing your question directly, but what the article described was a "fuse"-based filesystem. The entire filesystem runs as a program in userspace using the fuse framework (yum install fuse or aptitude install fuse), instead of in the kernel. A lot of popular filesystems use this these days including sshfs including ntfs-3g. And actually you can indeed put them in fstab, if you make sure there's an appropriate /sbin/mount.<fsname> script or program. I use sshfs quite a bit, though I always invoke it from the command-line because of its nature (accessing arbitrary remote servers on an irregular basis). I've often wished that there were fuse versions of every filesystem in development, so I could easily test them on older distros without having to compile new kernels. Like for btrfs. It would also allow file systems to be ported to OS X and maybe even Windows. I know performance would not be as good. I think it would still be an interesting development tool. /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
