Not in GEOM, but in GPT labels implementation. It should be part of
PART class, not LABEL class. Because of this, when one opens
corresponding ada<X>p<Y> for writing, both gpt/<label> and gptid/<uuid>
disappear. When one opens gpt/<label> or gptid/<uuid> for writing, the
other one disappears. Another issue is that when you change your label,
add it or remove it, it is not automatically visable in gpt/, one needs
to retaste the entire disk.
