I just tested this on the latest CentOS AH, and it worked:
First, deploy the older version:
# atomic host status
...
* 2016-07-07 21:23:41 7.20160707 cd47a72eb5 centos-atomic-
host centos-atomic-host:centos-atomic-host/7/x86_64/standard
# atomic host deploy 7.20160610
...
# atomic host status

host centos-atomic-host:centos-atomic-host/7/x86_64/standard
Now, looking at /boot/loader/grub.cfg (or /boot/loader) we can figure
out the kernel/initrd:
# kexec -l /boot/ostree/centos-atomic-host-
# 5f3ab890b70e1a7a1eaa4a698fb9ad84b34944f79e328f22a2e40c77d8d7b2f6-

# kexec -e
...
$ vagrant ssh

Anyways I filed https://github.com/ostreedev/ostree/issues/435 to track
adding this.
