'ERROR: Unable to write privatekey' on current DevStack version

Hi everybody,

I just cloned and deployed the last version of DevStack and when running stack.sh the following output appears when creating certificates and sourcable rc files per tenant/user - that's it, when create_userrc.sh gets called.

This situation is noticeable because the scripts pauses waiting for an input (or at least I didn't give it enough time), and when pressing enter it proceeds to next .pem.

A non-elegant solution is removing certificates directory, devstack/accrc, before running stack.sh.

I checked the script but nothing caught my attention.

Does someone have an idea of why is this happening?

Thanks a lot in advance
