When trying to copy files onto a Virtio-9p filesystem[1][2] int the host
using something like the template module, ansible throws an error that
says something like:
invalid selinux context: [Errno 95] Operation not supported
Adding 9p to the list of exceptional filesystems forces ansible to not
try to set an SELinux context on copied files.
[1] such as one mounted in a qemu VM, using:
# http://www.linux-kvm.org/page/9p_virtio
qemu-kvm [...] -virtfs local,id=apps_dev,path=/host/dir,security_model=passthrough,mount_tag=host_dir
