My conclusion from reading your comments as of now:
1) "Pandora OS" qualifies as the OS name, as it's different enough (WizardStan), and other suggestions were meant quite humorously (Anders, Pangstrøm, Angora).
2) a) For occasions were compactness is appreciated and it is clear that the discussion concerns OpenPandora's OS and/or software (i.e.: its own issue tracker) we can use the mere numerical notation R.H.S (Release, Hoftfix, Sub-number).
B) In more general contexts such as the web, the long form "Pandora OS Releasename Hotfix H S" (H being the hotfix number, S being the sub number) can be used.
Nevertheless using the general term "Pandora" accompanied with a video game name as a release name (such as Zaxxon), which by nature then changes with every release, possibly brings rather ambiguous web search results (SEO and ranking), whereas PandoraOS or "Pandora OS" accompanied with a number probably gets quite reliable results. On the other hand the term "Hotfix" together with these identifies context quite well I guess.
However, I won't stress my mind with external naming conventions (2b) anymore, as long as the internal short naming convention (2a) is now clear. I will use it in the issue tracker from now on. Btw,
I put so much detailed efforts into issue reporting (about 25 over the last 2 months!), and got almost no reactions! More involvement would be appreciated from my side!
