Can not use mklabel filesystem specification feature |

I'm trying to use the possibility of mkpart to specify the file system type,
with the non interactive interface (--script)
First point is pure documentary :
https://www.gnu.org/software/parted/manual/parted.html#mkpart indicates :
mkpart [part-type fs-type name] start end
man mkpart indicates:
mkpart [part-type name fs-type] start end
name and fstype have been switched between the two docs.
All versions 3.2 !??
Anyways, it seems that using the name always fail
Second point :
I expect this line
#parted --script /dev/sda unit s mkpart primary ext4 2048 208896
to create a partition with a file system set as ext4.
I don't expect it to be initialized, but just to have the display like :
Number Start End Size Type File system Flags
1 2048s 208896s 206849s primary ext4 lba
Instead I get this :
Number Start End Size Type File system Flags
1 1049kB 107MB 106MB primary
Now using the commdand console interface everything is ok :
# parted /dev/sda
GNU Parted 3.2
Using /dev/sda
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) unit s mkpart primary ext4 2048 208896
(parted) p
Model: ATA ST32000641AS (scsi)
Disk /dev/sda: 3907029168s
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:
Number Start End Size Type File system Flags
1 2048s 208896s 206849s primary ext4 lba
This should be part of an automated workflow.
I've also tested things like
echo "unit s mkpart primary ext4 2048 208896 q" | parted --script /dev/sda
and
parted --script /dev/sda <<< "unit s mkpart primary ext4 2048 208896 q"
without success.
It also fails without --script.
What am I missing ?
Regards,
Pierre

The docs have been fixed for about a year now and will appear in the
next release. The msdos partition table does not support names.

That is because the partition in fact, contains no filesystem. Parted
used to re-read the disk after every command, but in the next release,
will no longer do this and so will preserve the "ext4" filesystem
setting until you restart parted.
