Bind Mount Directories

Bind-mounts are more robust than symlinks, especially when dealing with directories on removable storage: they use time-tested failsafe mounting techniques. Bind-mounted directories can also provide special permissions to users that differ from the source directory.

For example, let's say that you want to link a folder on the external USB hard drive to vsftpd's  folder.

  First, create the source folder on the external hard drive: sudo mkdir /media/usbdisk/ftp   Next, (if necessary), create the destination folder on the system: sudo mkdir /var/ftp/pub   After that, (if necessary) give the target user permissions over this specific directory. In this example, the target user is, in group. If you don't need to run programs from this folder, use. If you do, use. sudo chown ftp:ftp /media/usbdisk sudo chmod 644 /media/usbdisk   Finally, add this bind mount entry to the, so it will be mounted on boot every time. /media/usbdisk/ftp          /var/ftp/pub                 none    bind    0 0
