Yes, it is lots of fun.

I don't quite understand what you are asking. You create a mirror (with
"gmirror label...") and then a GPT on top of it, and then you can't see
the GPT labels? If so, then it unfortunately reminds me of this thread:

If it's something else, please explain with more details.

No, it's a chicken-and-the-egg problem - to use sysctls you need a
working system. Loader tunables could work but it's at best a cosmetic
request. And we can't make glabel modular (so, e.g. you load
GLABEL_GPTID or something) because it will break it for people who
expect it to "just work" for all labels at once (that's kind of the
point of glabel).
