Comment 4 Pino Toscano 2016-11-08 17:37:35 UTC

The fix is not complex, but a big long and possibly invasive at this point.
Also, this is mostly providing more hints/errors for wrong situations, like specifying --format after the disk it should specify the format for. The real "fix" is to just specify the arguments in the right order, which is how things are supposed to work.

For the reasons above, I'm inclined to not fix this bug at this point.
