def includes_whitespaces?(mount_line)
  ws = mount_line.match(/^(.+)\son\s(.+)\stype\s.*$/)
  ws.captures[0].include?(' ') or ws.captures[1].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
