This sounds confusing to me, what about something like:
"\"%s\" has a default partition, cannot add a new partition."

Note that this comment belongs to patch 0002, and it will go away
in case we are going to have extended functionality i.e. patch 0003,
as in that patch we allow user to create a new partition even in the
cases when there exists a default partition.
