Thanks for your concern, but we don't see a point in just removing it in git because it doesn't really help. the key is in several branches, in our iso file, every rockstor rpm in our yum repo and not to mention lot of users who have downloaded rockstor.
We changed the key in our live demo, but for our users we'll roll out the fix in the next update. As part of that fix, we'll also remove the key file from git.
I think that's a reasonable plan. Hope I am not missing something.
