Well I've narroed it down to the following patch from Andrew:


Basically, that leads setup_arch to return saved_command_line as _the_
command_line. We then run parse_args() against it which assumes it may
irrevocabaly change command_line. Previous to this patch
saved_command_line and command_line were separate and this was not an issue.

It feels like we should be following the model in the newly added
parse_early_parms() and taking a local copy of the command_line here.
