Users of CentOS Atomic 7 will hit this error on upgrading now:
# atomic upgrade

error: fsetxattr: Invalid argument
What's happening here is that this is a full atomic switch from a CentOS 7.0 to CentOS 7.1 base - but we're using the old selinux policy to do it. The 7.0 SELinux policy had a bug with respect to rpm-ostree that caused a domain transition to not occur.
You can work around this with:
# runcon -r system_r -t install_t atomic upgrade
