I have bind mounts configured in my /etc/fstab. The source (i.e. where the files physically exist) is on a removable USB drive.

Right now it works but I have to mount/unmount everything individually when I plug/unplug the drive. I would like to be able to have the bind mounts follow the state of of the USB drive automatically.

Is there a way?

Edit here is relevant section of fstab:

/dev/mapper/external-crypt	/mount/external		auto	nosuid,nodev,nofail,x-systemd.device-timeout=5	0 0
/mount/external/realfolder	/home/user/folder	none	bind,nofail	0 0

So when I run sudo mount "/mount/external" I want sudo mount /home/user/folder to be implied; likewise for umount.

I think systemctl might be a way because I have read that things are dependent on other things but beyond that I don't know how to organize it.
