|    |  Thanks! But...

|    |  # bin/gpt-current sd0 biosboot -a -i1
|    |  gpt-current: unknown option -- a
|    |  Usage: gpt-current <device> biosboot [-c bootcode] [-i index] [-L label]
|    |  #  
|  Believe it or not, the correct usage is still "gpt biosboot [opts] device
|  The usage message prints it in the order you show whenver the command
|  name is not "gpt" (which it isn't for you).   I have no idea why, I see
|  no code to support the devide first ordering (whatever the command name is)
|  I suspect it is an artifact of that you're seeing (though I get a
|  different message when I try it that way.)
|    |  and gpt.8 renders to
|    |  
|    |       gpt biosboot [-ac bootcode] [-i index] [-L label]
|  Fixed.
|  ALso, thanks for tracking down this problem, I noticed it back in Dec 2013,
|  and worked out the fdisk (to put a regular MBR there) followed by gpt
|  create (to convert that to a PMBR) solved the problem, and had worked out
|  that gpt create on an uninit'd drive was not setting something properly,
|  but I never got as far as working out what that was.
|  I think though that Christos new -a flag should be changed (probably to -A)
|  (througout) to avoid clashes with the "-a alignment" option that is
|  used everywhere else (even the biosboot usage has a "[-a alignment]"
|  option already in it .. just #ifdef'd out, the new -a would prevent that.)

Good idea.
