podman-image-unmount - Unmount an image's root filesystem
podman image unmount [options] image [...]
podman image umount [options] image [...]
Unmounts the specified images' root file system, if no other processes are using it.
Image storage increments a mount counter each time an image is mounted. When a image is unmounted, the mount counter is decremented, and the image's root filesystem is physically unmounted only when the mount counter reaches zero indicating no other processes are using the mount. An unmount can be forced with the --force flag.
All of the currently mounted images will be unmounted.
Force the unmounting of specified images' root file system, even if other processes have mounted it.
Note: This could cause other processes that are using the file system to fail, as the mount point could be removed without their knowledge.
