Creating FAT32 partition in script mode with GNU Parted 1.4.16?

[Carl Soeder]

I'm using GNU Parted 1.4.16 on RedHat Linux and want to create a FAT32
partition in script mode.

I found I can create a FAT32 partition in non-script mode by answering yes
to the prompt after giving a command such as:
  parted /dev/sdm mklabel msdos mkpartfs primary fat 0 1000 set 1 boot on

But when I use the parted command in script mode such as:
  parted -s /dev/sdm mklabel msdos mkpartfs primary fat 0 1000 set 1 boot on
parted creates a FAT16 partition.

Parted 1.4.16 doesn't appear to accept fat32 as file sytem type on the
command line. Is there a way to use the -s option and create a FAT32
partition with Parted 1.4.16?

Thanks,
Carl
