sorry, why you say that's confusing/incorrect?
by that I just want to say that we support both follow commands:
  sdcard-mounted.sh --serial serial
  sdcard-mounted.sh --s serial

And I just borrow this code from lava-partition-disk in lp:lava-master-image-scripts,
did not see the difference between the usage of them.:(

changed to use $(basename $0)
