I want to mount two disks or directories into a single mount point. I saw some article online which mentioned bindfs, I had a look at it but I don't understand how it can help.
Another article shows how to mount two disks into a single directory using this mount option: -o union. I tried those instructions and they don't seem to work.
My goal is to mount a disk into an existing directory of an already mounted disk and see both files from the mounted disk and the directory.
The solution proposed is not working, the content of the disk hides the content of the target directory.
