Comment:
Perhaps `chroot-style/uchroot` can check the mount point's filesystem and error out if with a explicit message.
Some lines using `findmnt` from `util-linux` can be used to tell a path's file system:
```
#!/bin/bash
path=$PWD
while [ -z "$FSTYPE" -a ! -z "$path" ]; do
	eval $(findmnt -P "$path")
	path=${path%/*}
done
echo "$FSTYPE"
```
