As I tried to explain in my previous mail, I'm claiming that:

a/ it's impossible the ordering fixed your problem

   (I actually hacked up agetty to print out the structure the
   command-line parsing is stored into and verified that the structure
   ends up exactly the same no matter which order you give the arguments
   in. Before doing that I also checked the code and could not see any
   reason why the argument ordering detection code would not work.)

b/ You changed (atleast) 2 things, not only the order.

   (For example, in your example with order reversed you also dropped
   all alternative speed settings and just gave a single speed setting
   instead of a list.)

Given this there's no evidence that implementing your suggested change
will fix anything. Please provide more input. Try to change one thing
at a time in your testing to isolate which change actually fixes your
problem.

Andreas Henriksson
