sudo apt install bindfs

sudo bindfs -u ftpdrop -g user --create-with-perms=0775 /media/user/hdd/cam66/ /home/ftpdrop/Videos/cam66

Bindfs is a FUSE-based filesystem utility for Linux and macOS that mirrors a directory to another location, similar to mount --bind, but with the ability to alter file permissions, ownership, and access rights in real-time. It is commonly used to make directories read-only, share files among users without altering group settings, or modify permissions for specific processes.

Why this is good:

    Zero Extra Space: It takes up 0 bytes of extra space on your OS drive.

    Solves the Security Problem: You can now lock ftpdrop inside their /home folder (using "Chroot" in your FTP/SSH settings). The app thinks it’s in a safe, tiny home folder, but the heavy video files are actually landing on your big NTFS drive.

    Bypasses Parent Permissions: You don't have to give the ftpdrop user access to your private /media/user/ folder anymore. They only see the "portal" in their own home.

sudo ls -ld /home/ftpdrop/Videos/cam66

drwxrwxrwx 1 ftpdrop user 12288 Jan 29 14:17 /home/ftpdrop/Videos/cam66

sudo -u ftpdrop touch /home/ftpdrop/Videos/cam66/testfile.txt
