In general I agree with the idea that parted should only deal
with the partition table and other tools do the other tasks.

The problem here is that calling wipefs after creating a
partition with parted can fail (it is a race condition) since
e.g. udev has already activated something based on old
signatures.

To demonstrate the problem I have attached a script that fails
when started the second time. Meanwhile there is also the
ANACONDA property in udev but it only disables auto-assembly of
RAIDs. It is also a system-wide property so could have bad side
effects on other processes.

Thanks, that's fine. I will likely post a few more patches.
