Well a) it's written down in a policy now so it's TOTALLY not going to
change ;), and b) I didn't know the right way to do that :) Do you just
run the string through split twice, or is there something clever? AFAICS
you can't pass multiple alternate separator fields with str.split, but I
may have missed it in the docs.

The policy is
https://fedoraproject.org/wiki/User:Adamwill/Draft_fedora_image_naming_policy . As currently written at least, it strictly reserves - as a field separator:

Fields may only contain ASCII alphanumeric characters and underscores.
Particularly of note, the character '-' is reserved for use as a field
separator. No field may itself contain that character. 

so if it actually continues to be followed, this'd be safe. Although! It
did just occur to me to wonder what RHEL does...I have beta and RC1
images of RHEL 7 here and they both seem to use just '7.0' as the
Version in /.buildstamp , so we probably don't have to worry there, but
I don't know for sure.

Who knows what the future may bring ;)

Nice catch - I didn't spot that. In fact it is using _ , so I think it
does need fixing as well. See

I forgot to note that I believe this patch should be considered part of
fixing https://bugzilla.redhat.com/show_bug.cgi?id=1134524 and hence
it's effectively a release blocker and can/should go to f21-branch.
