Description Olliver Schinagl 2019-01-10 07:18:13 UTC 
Bind mounting a file is a legal possibility with mount since quite a few years. With the rise of docker, bind mounting files is not very uncommon anymore and many docker containers use busybox as their toolset (via alpine).

mountpoint from util-linux quite happily checks if a file is a mountpoint, but the busybox variant sadly complaints that the path is not a directory.
