def includes_whitespaces?(mount_line)
  # Split the mount_line by " on "
  parts = mount_line.split(" on ")
  # Check if either part contains spaces
  parts.any? { |part| part.include?(" ") }
end

#parse_mount_options(mount_line, compatibility = false) ⇒ Object

this parses the output of mount command (only tested on linux) this method expects only one line of the mount output
