Nope. Fabric's not an expect clone, nor does it know how to move the
mouse or anything :)

This is always the right answer (for any scripting tool -- not just
Fabric.) You need to understand the installer well enough to figure
out how to script it so it can be run non-interactively.

For example, on Debian Linux systems you can use the "debconf" system
to pre-set any question an installer might try to prompt you for.
Takes a little bit of researching to find out which settings those are
for the package in question, but it is definitely doable.

Sometimes it's enough just to tell the package manager to run
non-interactively (e.g. DEBIAN_FRONTEND=noninteractive apt-get install
xyz) or to give it a "always say yes please" flag like -y. Many
packages will look at these hints and skip prompting you entirely.

But again, this is all 100% Fabric agnostic and depends entirely on
your remote system :)

Good luck,
Jeff
