This is an option that should be removed from nova, as it is a large
burden on the compute node and is specific to filesystem types the host
can mount.

Use config drive or the metadata service to expose those details to
your instance (cloud-init will gladly read these things for you and is
installed on most stock Linux cloud images). Then, as you say, you can
SSH in or let a pull system like Puppet with a puppetmaster customize
the instance.

I'd actually recommend turning off file injection entirely.
