When I use ftpfs to mount a ftp site and then bind /n/ftp to another location. All appears to work fine in /n/ftp and in the other location. When I type ns, I can clearly see the pipe bind for ftpfs mounted to /n/ftp. When I unmount /n/ftp I can type ls on /n/ftp and not see anything there. But if

I guess what confuses me when dealing with something like ftpfs, is that it seems to behave differently than other types of binds. Examples I've used in the past involve simple binds like this. I create 4 directories, let's say dir1, dir2, dir3, dir4. Inside dir1 and dir2 I have files. I can then:

oh yeah, it seems to do a pipe bind to the other location, only when binding to the root. If I bind to /n/ftp/directory, it doesn't show the pipe bind in ns. On Sat, Dec 6, 2008 at 5:52 PM, Brad Frank <[EMAIL PROTECTED]> wrote: > I guess what confuses me when dealing with something like ftpfs, is
