Of course the > directories themselves can not be hard linked, Actually, you *can* hard-link directories (if root). But it's just not advisable unless you are an *expert*. Hard linked directories can cause all kinds of strangeness, and potentially corrupted filesystems. In addition the meaning of "." and ".." may be surprising to you, or to some software. [in fact the "." and ".." directories are in fact just hard links to the real directory, which the kernel creates for you automatically.] See the man page for ln(1), and for link(2). > but is there a simple way to > create a duplicate directory tree and then make hard links to all of the > files? Many options... The -l option on the cp(1) command. Use a gtar-pair with the -H option, like, gtar -C srcdir -cHf - . | gtar -C destdir -xHpf - Use rsync, like, rsync -av /srcdir /destdir (It's really the -l option on rsync, but the -a implies -l) Or, if you want symlinks instead of hardlinks, see the lndir(1) command. > The links are to provide ftp access to files in a chrooted area on the same > partition. Then another option, is to use loopback mounts. That has the advantage in that files can be added/removed without having to redo link maintenance. -- Deron Meranda
