I'm attempting to place a simple shell script in user data to perform post-boot configuration. This fails since I'm unable to execute anything within user data.

Well the --regex=.* above is just to avoid debian's implicit
filtering rules, and run all scripts.

The fedora run-parts will run everything anyway
(only avoiding obvious things like rpmsave files etc.)

So I'd change cloud-init to support the existing system,
which I've done in a patch attached to:
https://bugzilla.redhat.com/show_bug.cgi?id=795998

cloud-init upstream would need a more general tweak
to support both systems.

cheers,
