bindfs

Mount a directory elsewhere with different permissions. More information: https://bindfs.org/docs/bindfs.1.html.

• Mount a directory with same permissions:

sudo bindfs {{path/to/directory}} {{path/to/mount_point}}

• Map filesystem objects owned by user1 to be owned by user2 (also applies in reverse to newly created files):

sudo bindfs --map={{user1}}/{{user2}} {{path/to/directory}} {{path/to/mount_point}}

• Unmount a directory:

sudo umount {{path/to/mount_point}}
