I've a LUKS container that's opened from a keyfile stored on a USB stick.
Is it safe to remove the USB stick once the container has been opened, or
must the keyfile remain available to LUKS until the container is closed?
(in my tests it worked fine, but I don't want to risk losing data if it's
not allowed).
