modprobe treats "-" and "_" interchangeably, thereby avoiding frequent errors because some module names contain dashes and others underscores. Because modprobe@.service unescapes the instance name, an attempt to start "modprobe@dm-crypt.service" will run "modprobe -abq dm/crypt", which is doomed to fail. "modprobe@dm_crypt.service" will work as expected. Thus unescaping the instance name has surprising side effects. Use "%i" instead.
