This is due to line 227 of ./cloudinit/config/cc_mounts.py::

short_name = os.path.basename(device)
sys_path = "/sys/block/%s" % short_name

if not os.path.exists(sys_path):
LOG.debug("did not find entry for %s in /sys/block", short_name)
return None

The sys path for /dev/sda1 is /sys/block/sda/sda1.
