Mounting a directory in a directoryPosted: March 10, 2016
You can mount a directory inside another directory. It is a functional analogue of having it hard linked, which is normally available only for files.
You can do it either by running a command:
mount --bind source_dir destination_dir
or, if you want it to be permanent, adding a line to your /etc/fstab:
source_dir destination_dir none defaults,bind 0 0
